Calculate heater sizeCare Notes
- Give it space: at least an 80 gallon tank with sturdy rock piles for territories and plenty of open sand for cruising and hunting.
- Run hard, alkaline water in the Tanganyika range: 24-26 C, pH 7.5-8.5, and 10-18 dGH.
- Feed as a carnivore: quality pellets and frozen meaty foods; this fish naturally hunts shrimps and other invertebrates.
- Skip ornamental shrimp and other inverts as tankmates, and avoid small, timid fish that resemble prey.
- For companions, stick to robust, similarly sized cichlids that thrive in hard, alkaline water, and use rockwork to break lines of sight to reduce clashes.
- Expect a bold, semi-aggressive, territorial personality; give multiple rock refuges so it can claim a spot without constant fights.
- Long-jawed and stealthy, it really comes alive with open sand lanes for ambush runs paired with solid rock cover.
Compatibility
Good Tankmates
- Medium, rock-dwelling Tanganyikans like Julidochromis that stick to crevices and can hold a territory
- Altolamprologus calvus/compressiceps that work rock faces and are steady, not hyperactive
- Cyprichromis spp. midwater schools that use the open water above the rocks; choose adult-sized fish
- Neolamprologus leleupi and similar robust lamprologines of comparable size; provide separate caves
- Tanganyikan Synodontis catfish such as S. lucipinnis/petricola that tolerate high pH and keep to the bottom
- A single established pair of Jabarichromis pfefferi in a large rock-and-sand layout; avoid multiple males
Avoid
- Shrimps, snails, and other invertebrates that will be hunted
- Tiny shell dwellers and juvenile fish that fit in the mouth or cannot defend a territory
- Delicate sand-sifters like Xenotilapia or Enantiopus that are stressed by assertive predators
- Hyperactive or very aggressive grazers like Tropheus and Malawi mbuna that cause nonstop chasing and diet conflicts
Pfeffer's cichlid (Jabarichromis pfefferi) is a shrimp-hunting Tanganyikan predator with a long, sleek jaw profile and a bold, territorial personality. It reaches about 14 cm, lives 6-10 years, and suits advanced keepers who enjoy stealthy hunting behavior more than flashy colors.
Origin and natural habitat
This species comes from Lake Tanganyika in East Africa. It is built for stalking and striking at crustaceans, working the transition between rockwork and open sand. Like many Tanganyikan cichlids, it is a maternal mouthbrooder.
Aquarium setup and water conditions
Give a single adult at least 80 US gallons. Layout matters: stack solid rockwork to form caves and firm boundaries, but leave generous open sand for hunting runs. A fine sand substrate best matches its natural behavior.
- Temperature: 24-26 C
- pH: 7.5-8.5 (hard, alkaline)
- Hardness: 10-18 dGH
Aim for clean, stable water and plenty of swimming space. Hard, alkaline conditions are not optional for this species; it really comes into its own in the same chemistry it evolved in.
Match it only with fishes that also require hard, alkaline water. Do not mix with softwater species.
Diet and feeding
A carnivore that preys on shrimps and other invertebrates. In the aquarium it accepts quality carnivore pellets and frozen foods.
- Staples: mysis, krill, chopped prawn, quality carnivore pellets
- Occasional variety: other clean frozen invertebrates
- Avoid: feeder fish and carbohydrate-heavy, plant-based pellets
Feed moderate portions and watch body condition. Its long, precise strike is best engaged with sinking or slowly moving foods placed over open sand.
Behaviour and tankmates
Semi-aggressive and strongly territorial, this fish uses rock lines as borders and patrols nearby sand for prey. It will hunt shrimp and other small invertebrates.
- Choose robust, similarly sized fishes that tolerate firm personalities.
- Select tankmates that are too large to be treated as prey.
- Provide clear sight breaks so rivals can avoid each other.
- Avoid timid species, small community fish, and all ornamental shrimp or crayfish.
Crustaceans are viewed as food. Expect shrimp, crabs, or crayfish to be hunted.
Common problems and how to avoid them
- Water chemistry mismatch: Soft or acidic water leads to poor condition. Keep pH 7.5-8.5 and hardness 10-18 dGH.
- Cramped layouts: Straight sight lines and no open sand amplify aggression. Use rock boundaries and leave open sandy lanes.
- Inadequate diet: This species needs meaty invertebrate-based foods, not general community flakes or plant-heavy pellets.
- Overstocking: Too many similar cichlids in limited space magnifies territorial fights. Keep stocking conservative for the footprint.

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.
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
A West African dwarf cichlid from Guinea's Bandi River, this fish shows crisp vertical bars and spotted fins with red highlights. Females have a bold black spot at the base of the tail, and pairs guard eggs and fry in caves, which makes their parental behavior fun to watch.
Betta
Betta splendens
Betta fish, also known as Siamese fighting fish, are popular for their striking colors and flowing fins. They are known for their territorial nature, especially males, which can display aggressive behavior towards each other.
Blackhawk catfish
Wallagonia micropogon
Wallagonia micropogon is a giant Southeast Asian sheatfish with an eel-like body and a huge, scoop-like mouth for hunting other fish. It is native to the Mekong and middle Chao Phraya basins and was long confused with Wallagonia leerii, which makes IDs and care notes tricky. Stunning as a juvenile but it grows to true megafish size, so it is only realistic for expert keepers or public aquariums.
Boulenger's Featherfin Tetra
Bryconaethiops boulengeri
A big, fast African tetra from the Congo River basin, it cruises the mid-to-upper water in active groups and flashes a bold broken stripe along its flanks. In the wild it hunts insects at the surface and can leap, so aquariums need tight lids. Keep it with robust tankmates it cannot swallow.

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.
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.
Arrowhead puffer
Pao suvattii
Pao suvattii is that sneaky Mekong puffer that likes to sit low and ambush food, and it has that super recognizable arrow/V pattern on its back. Gorgeous fish with tons of personality, but it is absolutely not a community guy - plan on a solo, species-only setup if you want everybody to stay in one piece.
Bishop toothcarp
Brachyrhaphis episcopi
This is a tiny Panamanian livebearer that does best when you treat it more like a shy wild fish than a fancy guppy-lots of cover, calm vibes, and really clean water. The fun part is watching the males posture and spar while the females cruise around dropping fully-formed fry about once a month.
Black morpho tetra
Poecilocharax weitzmani
Poecilocharax weitzmani is one of those tiny blackwater oddballs that acts more like a little darter than a typical tetra - it hangs low, darts between cover, and the males can get pretty showy with fin-flares. The really cool part is they are cave breeders with male brood care, which is not what most people expect from a small characin. Give them very soft, acidic, super-clean water and lots of leaf litter and hidey holes, and they settle in and start showing their best colors.
Black Neon Tetra
Hyphessobrycon herbertaxelrodi
Black neons are one of those little tetras that look kinda understated until the light hits them-then that bright stripe pops and they shimmer when the school turns together. They're super chill, always cruising mid-water, and they make a tank feel "alive" without being hectic. If you keep a nice group, they get bolder and you'll see way more of their personality.
