About the Striped Krib / Nigerian Red Krib
P. taeniatus is one of those West African dwarf cichlids that'll act totally chill most of the time, then flip the switch into "serious cave owner" the moment it wants to spawn. The fun part is the local color forms ("Nigeria Red", "Moliwe", etc.) and the pair-bonding-when they settle in, you really get to watch a little cichlid soap opera play out around their cave.

Calculate heater sizeCare Notes
- Give them a footprint more than height-think 20 long/75L+ for a pair-and pack in caves (coconut shells, rock piles, flowerpots) so each fish can claim a spot.
- They do best in soft, slightly acidic to neutral water (roughly pH 5.5-7.0, low-to-moderate hardness). If your tap is hard/alkaline, consider mixing RO or using botanicals to lower/soften water more naturally rather than chasing pH with quick-fix chemicals.
- Fine sand is awesome because they love scooping and sifting; use sturdy plants (Anubias/Java fern) and lots of wood/leaf litter so they can break line-of-sight when moods change.
- Feed small portions 1-2x a day: quality pellets/flakes as the base, then rotate frozen foods like brine shrimp, bloodworms, daphnia-too much rich stuff all the time just makes them bloaty and aggressive.
- Best tankmates are calm midwater fish that won't harass their cave (tetras, rasboras, pencilfish) and bottom dwellers that keep distance; avoid other cave-spawning cichlids and pushy catfish that barge into their nests.
- When they pair up, they get territorial fast-expect them to "own" half the tank-so don't cram multiple pairs unless the tank is big with lots of rock/wood walls breaking things up.
- Breeding is fun and pretty easy: they'll lay eggs in a cave and the parents will march the fry around; keep the intake covered with a sponge and feed the fry baby brine shrimp/microworms once they're free-swimming.
- Watch for shredded fins and missing scales (usually from cave disputes) and for digging that undermines rocks-set stones on the glass bottom, not on sand, because these guys will excavate like little bulldozers.
Compatibility
Good Tankmates
- Midwater schoolers that can take a little attitude, like Congo tetras or sturdy barbs (think rosy barbs). They keep moving, don't camp in the krib's space, and the kribs usually ignore them once everyone settles in.
- Rainbowfish (Boesemani, turquoise, etc.). Fast, confident, and not easily bullied-great "dither" fish so the kribs don't run the whole tank.
- Peaceful top/mid fish like hatchetfish (especially marbled/silver). They hang up top, kribs stay lower, so they're basically living in different zip codes.
- Calm, armored bottom buddies that don't compete for caves-Corydoras work in bigger setups, especially if you've got multiple hides and the kribs aren't actively raising fry.
- Bristlenose pleco (Ancistrus). In my experience they're one of the safer "bottom" choices because they're tough, mind their own business, and don't freak out when a krib does a bluff charge.
- Some peaceful, non-cave-invasive catfish can work (e.g., certain smaller Synodontis), but avoid bottom fish that will repeatedly enter/compete for caves-especially during spawning.
Avoid
- Other cave-spawning dwarf cichlids (Apistogramma, other Pelvicachromis, ram cichlids). This is where fights start-same real estate, same nesting sites, and once a pair bonds they'll try to evict the neighbors.
- Slow, fancy-finned fish (bettas, guppies/endlers with big tails, longfin anything). Kribs aren't "fin nippers" like some barbs, but they are pushy and will absolutely harass slow fish that won't get out of the way.
- Nippy or aggressive fish (tiger barbs, serpae tetras, some mean danios, or bigger cichlids). Either they'll stress the kribs nonstop or you'll get a tank that's just constant drama.
- Shrimp and tiny bottom fish that poke around caves (dwarf shrimp, small gobies, tiny loaches). Especially if the kribs spawn-anything near the cave gets treated like an intruder and may just disappear.
1) Where they come from
Striped kribs (Pelvicachromis taeniatus) come from West Africa—think Nigeria/Cameroon area—living in slow, plant-choked streams and creeks with lots of roots and leaf litter. That “messy” bottom is basically their comfort zone, and it explains why they love caves and boundaries.
You’ll see a bunch of locality names in the hobby (like "Nigeria red"). Keep the strain/location consistent if you plan to breed—mixing locales makes confusing-looking offspring and people get salty about it.
2) Setting up their tank
These are dwarf cichlids with big opinions. Give them a tank that lets them claim a spot and still lets everyone else get around them. For a pair, I’d start at 20 gallons long as a comfy minimum; 29+ is even easier to manage if you want tankmates.
- Footprint matters more than height—long tanks beat tall ones.
- Fine sand is my favorite substrate. They sift and dig, and sand keeps their mouths/gills happier than sharp gravel.
- Hardscape = territories. Use wood, rocks, and plants to break up lines of sight so aggression doesn’t stay “on” all day.
- Caves: give options. Coconut halves, small clay pots on their side, or rock caves all work.
Water-wise, they’re fairly forgiving compared to some West African fish, but they do best in clean, stable water. I’ve kept them in the mid-70s°F (around 24–26°C). Neutral-ish water is usually fine; if your tap is liquid rock, they can still live, but breeding can get a little pickier.
If you’re fighting aggression, add more "stuff" not more water changes. A couple extra caves and a chunk of wood that blocks sightlines can change the whole vibe overnight.
They dig. If you stack rocks, set them on the tank bottom (or on egg crate) before the sand goes in. Don’t trust a krib not to undermine your rock pile.
3) What to feed them
They’re easy eaters once settled, but they color up and breed way more reliably with variety. Mine always looked best on a mix of quality pellets plus frozen foods.
- Daily staple: a small sinking cichlid pellet or good community pellet (they like to pick off the bottom).
- Frozen rotation: bloodworms (not every day), brine shrimp, daphnia, mysis.
- If you’re conditioning for breeding: bump frozen foods for 1–2 weeks, small portions, more often.
- Occasional veggie isn’t a bad idea (spirulina flake, blanched zucchini), but they’re not primarily herbivores.
Feed them like little pigs—but in tiny servings. Two small feedings beat one huge dump. It keeps water cleaner and you get better behavior and color.
4) Behavior and tankmates
Most of the time they’re confident, curious, and fun to watch—lots of posturing, little “dances,” and they’ll rearrange the sand like they pay rent. The mood changes fast if they pair up or decide a corner is theirs.
With tankmates, think calm and fast. You want fish that won’t bully them, but also won’t just sit there and take it if the kribs get spicy. Midwater schooling fish usually work great because they keep out of the cave zone.
- Good matches: larger tetras (depending on your water), Congo tetras (bigger tanks), rainbowfish, peaceful barbs, rasboras, hatchetfish.
- Bottom-dwellers: use caution. Corys can get harassed around spawning time. Bristlenose plecos usually do okay if there’s space and extra caves.
- Avoid: slow long-finned fish (gouramis, fancy guppies) and other cave-spawning cichlids in the same footprint.
If they spawn, they’ll defend a radius around the cave. In a smaller community tank that can turn into nonstop chasing. Have a backup plan (divider, spare tank, or be ready to rehome/move tankmates).
5) Breeding tips
Breeding is half the reason people fall for Pelvicachromis. If you give them caves and good food, they often take it from there. The female will usually show stronger color (that belly blush) and do a lot of “look at me” wiggling near the cave.
- Run multiple caves with different entrances. Let them pick their favorite.
- A pair that chose each other is way easier than a forced match. If you can, grow out a small group and let a pair form.
- Slightly warmer water and heavier feeding often flips the switch.
- Once you see them guarding a cave, keep your hands out of the tank unless you have to—maintenance becomes a full-contact sport.
They’re solid parents. You’ll see them shepherd fry around like tiny sheepdogs, and it’s honestly one of the coolest behaviors in the hobby. If you want to raise a lot of fry, a separate grow-out tank helps—community tanks usually turn it into a snack buffet unless the parents are extremely vigilant.
First foods: newly hatched brine shrimp is king, but microworms and powdered fry foods work too. Start small and frequent, and siphon gunk off the bottom so the fry aren’t living in soup.
6) Common problems to watch for
- Relentless bullying: usually from too few hiding spots or a pair in a tank that’s too small for tankmates. Add cover, break sightlines, or separate fish.
- “Mysterious” deaths after a big cleaning: they hate swings. Keep temp and parameters steady, and don’t deep-clean all at once.
- Bloat/constipation: often from overfeeding rich foods. Cut back, add some daphnia/roughage, and keep water clean.
- Ich/velvet: shows up after stress (new tankmates, temperature swings). Quarantine new fish if you can—it saves headaches.
- Fin damage: from territory fights. Usually heals fast with clean water and less crowding.
If one fish is constantly pinned in a corner with clamped fins, don’t wait it out. With kribs, “they’ll sort it out” can turn into a dead fish fast.
If you set them up with sand, caves, and a layout that gives them a clear home base, they’re a blast—tons of personality without needing a giant tank. Just respect that they’re small cichlids, not “community fish with stripes.”

American flagfish
Jordanella floridae
Jordanella floridae is that little Florida native with the red-and-cream striping that really does look like a tiny flag once a male colors up. They graze algae like champs (especially stringy/hair algae), but they have a bit of attitude - give them plants and space so the bossy behavior stays manageable. Bonus: the male guards the eggs and will actively fan them, which is pretty fun to watch.

Amur sculpin
Alpinocottus szanaga
This is a little coldwater sculpin from the Amur drainage - a bottom-hugging, rock-and-gravel fish that spends its day wedged under stones and darting out to grab food. Super cool behavior and attitude, but it is absolutely not a warm tropical community fish - it wants chilly, fast, oxygen-rich water and will bicker with other bottom fish.

Anitápolis livebearer
Jenynsia weitzmani
Jenynsia weitzmani is a freshwater anablepid livebearer endemic to southern Brazil (currently known only from the type locality near Anitápolis, Santa Catarina). Like other Jenynsia (onesided livebearers), reproduction involves lateralized mating morphology/behavior; aquarium care guidance is not well-documented for this species specifically.

Aracu-comum

Schizodon vittatus is a large South American anostomid (family Anostomidae). Reported maximum size is about 35 cm standard length; it is harvested/consumed in parts of Brazil and is not commonly covered by mainstream aquarium husbandry references.

Banded Leporinus
Leporinus fasciatus
Banded Leporinus are those torpedo-shaped, black-and-yellow striped fish that look like they're wearing a little prison outfit-and they stay on the move. They've got a ton of personality and they're awesome to watch cruising and picking at stuff, but they're also the kind of fish that will redecorate your tank and "taste test" anything soft-looking.

Bandi cichlid
Wallaceochromis signatus
Wallaceochromis signatus is a West African (Guinea, Kolente basin/Bandi River) dwarf cichlid that has appeared in the hobby under trade names such as “Bandi I/Bandi 1” and “Guinea” prior to/alongside its formal description. It is a cave-associated dwarf cichlid; provide cover and caves and expect heightened territoriality during breeding.

Ajuricaba tetra
Jupiaba ajuricaba
Jupiaba ajuricaba is a South American freshwater characin from the Amazon basin in Brazil (rio Negro, rio Solimões, and rio Tapajós basins). It reaches about 9.5 cm SL and is diagnosed by a narrow dark midlateral stripe, an elongated humeral spot, and an ocellated spot on the upper caudal-fin lobe. Wild specimens have been collected from blackwater forest streams and also oxbow-lake habitats.

Amapa tetra
Hyphessobrycon amapaensis
This is a tiny, super sleek little tetra with a clean red stripe down the side that really pops once its settled in. It does best in a planted, slightly tinted "creek-style" setup and looks way cooler when you keep a proper group so they school and flash that line together. If you can give it soft, slightly acidic water and a calm community, its an easy fish to fall for.

Anteridorsal Homatula loach
Homatula anteridorsalis
This is a benthic Chinese stream loach from Yunnan that lives right down on the bottom in clear, flowing water over gravel and rocks. Think of it as a "river tank" fish - it wants current, oxygen, and lots of surfaces to poke around on for bits of food and algae.

Armoured stickleback
Indostomus paradoxus
This is that goofy little "freshwater seahorse"-looking fish that just kind of perches and scoots around like a tiny armored twig. Its whole vibe is slow, sneaky micropredator - once its settled in, you will catch it stalking microfoods and doing these subtle little posture displays. The big trick is feeding: they do best when you can provide lots of small live foods in a calm, planted tank.

Arnegard's electric fish
Petrocephalus arnegardi
This is a little Congo River elephantfish (a weakly electric mormyrid) that cruises the lower parts of the tank and navigates the world with its electric sense. It stays small (around 9 cm) and has a clean silvery look with three dark marks that make it pretty easy to pick out among Petrocephalus.

Aroa twig catfish
Farlowella martini
Farlowella martini is one of those unreal-looking stick catfish that just vanishes the moment it parks itself on a branch. It is a super calm, slow-moving grazer that does best in a mature tank with lots of biofilm, gentle flow, and clean, oxygen-rich water - they are not great at competing at feeding time, so you kind of have to look out for them.
