About the Super Orange Aequidens
This is a small South American Aequidens from the upper Orinoco and Rio Negro area, and it stays way more compact than the big bruiser acaras people usually think of. The cool bit is that it has some really interesting breeding behavior reported in captivity - it will spawn on a surface, then move the wrigglers into the mouth for care, which is just wild to watch if you ever get a pair going.

Calculate heater sizeCare Notes
- Give them floor space, not height - a 40 breeder (or bigger) with sand and a couple rocks/wood pieces to break line of sight keeps the attitude down.
- They do best in warm, slightly soft to neutral water: shoot for 76-80F, pH around 6.5-7.5, and keep nitrates low with steady water changes (they get cranky in dirty water).
- Feed like a cichlid, not a piranha - quality pellets as the staple, then rotate frozen foods (krill, mysis, brine) 2-3x a week; skip feeder fish and go easy on fatty stuff like beefheart.
- They will redecorate: use tough plants (Anubias, Java fern) tied to wood/rock, or accept that rooted plants may get uprooted when they dig.
- Tankmates need to be sturdy and not tiny - good picks are medium-large tetras, robust barbs, larger Corydoras, or a bristlenose pleco; avoid small shrimp, guppies, and slow long-finned fish they can nip.
- If you keep a pair, expect territory drama when they spawn - they will claim a rock/flat surface, turn into bouncers, and may need their own tank or a divider once eggs show up.
- Watch for common cichlid issues: hole-in-the-head and bloat tend to show up when diet is junk or water is neglected; if they stop eating and get stringy poop, back off feeding and check water first.
Compatibility
Good Tankmates
- Other medium South American cichlids with similar attitude - like Severums or Blue Acaras. In a roomy tank with lots of sight breaks, they usually do that 'respectful neighbor' thing instead of nonstop beef.
- Tough, midwater schooling fish that are not bite-sized - bigger tetras like Congo tetras (yeah, not South American, but they hold their own) or good-sized silver dollars. The key is fast swimmers that do not panic and get pinned in a corner.
- Sturdy bottom crew that can take some attitude - larger plecos (like a bristlenose or a common-type in a big tank) that mostly ignore cichlid drama. Give them wood/caves so they can disappear when the cichlid is feeling spicy.
- Big Corydoras groups (think robust ones like bronze or sterbai) if the tank is big and the cichlid is not breeding. They work when there is lots of floor space and the corys are not constantly in the cichlid's favorite cave zone.
- Bigger, peaceful catfish like Raphael catfish or similar 'armored' types. They are night shift, keep to themselves, and a Super Orange Aequidens usually cannot bully them into caring.
- Another Super Orange Aequidens only if you are doing a confirmed pair and you are ready for breeding-level aggression. In my experience, random 'two of them' is how you end up rehoming one.
Avoid
- Tiny fish like neon tetras, ember tetras, guppy-sized stuff - anything that fits in the mouth is eventually a snack, even if it survives the first week.
- Slow, fancy-finned fish like angelfish, longfin livebearers, or anything that cannot zip away. They get stressed, and fin damage becomes a regular thing once the cichlid starts posturing.
- Nippy fin-biters like tiger barbs or hyperactive danio chaos squads. They wind the cichlid up, then everybody is mad and you get nonstop chasing.
- Hardcore brawlers - big Central American cichlids or very aggressive Africans. Different fight styles, and the Aequidens usually gets bullied or the whole tank turns into a war zone.
Where they come from
Super Orange Aequidens (Aequidens superomaculatum) are South American cichlids from warm, slow-moving waters with lots of leaf litter, roots, and fallen branches. The wild fish are more subtle, but the "super orange" look is a line-bred color form that still keeps the same cichlid personality: curious, food-motivated, and very aware of their space.
Setting up their tank
Give them room first, then decor. For a single adult, I would not go smaller than a 40 breeder-style footprint, and 55+ is nicer if you are doing tankmates. They use the bottom and midwater a lot, and they appreciate having a couple of zones they can claim.
- Tank size: 40B minimum for one, 55+ for community/tankmates, 75+ if you want a pair plus company
- Temp: 75-80F
- pH: roughly 6.5-7.5 (they are flexible if you keep it steady)
- Hardness: soft to medium is fine
- Filtration: strong, with real biological capacity - these fish eat big and poop big
- Flow: moderate; they do not need a river tank
Decor-wise, think "stuff to break up sight lines." I like driftwood, rock piles that are stable, and a couple of caves. Add a few flat stones or slate pieces if you ever want to try breeding. Sand is my favorite substrate with these guys because they sift and dig, and it is easier on their gills than chunky gravel.
If you want plants, pick tough ones and anchor them well. Anubias on wood/rock, Java fern, and big swords can work. Anything loosely planted will eventually get redecorated.
Make sure rocks are sitting on the glass or on a stable base, not perched on sand. Aequidens will excavate like they are getting paid for it.
What to feed them
They are classic omnivorous cichlids. Mine always did best with variety and a schedule that does not turn the tank into a nutrient soup. If you feed heavy (and you will be tempted), plan on more water changes.
- Staple: quality cichlid pellets (mix a couple sizes so they do not choke and everyone gets some)
- Frozen: mysis, krill, brine shrimp, chopped prawn, bloodworms as a treat
- Fresh: occasional earthworms or chopped nightcrawlers (rinse them)
- Plant matter: spirulina flakes/pellets or blanched zucchini/spinach once in a while
Go easy on fatty foods and constant bloodworms. A lot of "mystery bloat" stories start with rich food, overfeeding, and warm water all at once.
Two small feedings a day works better than one huge dump. Watch the belly line: you want them gently rounded after meals, not stuffed.
How they behave and who they get along with
They are not mindless killers, but they are still cichlids with opinions. Expect posturing, lip-locking attempts, and a lot of "this is my corner" energy, especially as they mature. They learn your routine fast and will beg like a puppy.
Tankmates depend on tank size and the individual fish. In a roomy tank with lots of cover, you can usually do other medium, confident fish that are not tiny and not overly aggressive.
- Good bets: sturdy larger tetras (silver dollars in big tanks), Congo tetras, larger barbs, rainbowfish (if water params overlap), medium catfish like Synodontis, bristlenose plecos
- Cichlid tankmates: other similar-temperament South Americans can work in big tanks, but be ready to separate if a pair forms
- Avoid: small tetras/guppies (become snacks), slow long-finned fish, super aggressive bruisers that will pin them in a corner
A single Super Orange often acts "friendlier" than a bonded pair. Once they pair up, their tolerance for roommates can drop fast.
Breeding tips
If you get a compatible pair, they will usually tell you. Colors intensify, they start cleaning a flat surface, and they get very focused on one area of the tank. Spawning is usually on a flat rock, slate, or in/near a cave.
- Give them choices: 2-3 flat stones and at least one cave
- Keep the water clean and steady; slightly warmer temps (around 78-80F) often gets them going
- Feed heavier on quality foods for a couple weeks before you try for a spawn
- Be ready with a divider or a spare tank if they decide every other fish must die
Parents can be excellent, but first-time pairs sometimes mess up and eat eggs or free-swimmers. If they are doing that repeatedly, you can pull the spawn and raise it yourself, but honestly I prefer letting them figure it out unless you are trying to produce numbers.
If they spawn in a community tank, dim the lights a bit and add extra line-of-sight breaks. It reduces the nonstop pacing and chasing.
Common problems to watch for
Most issues I have seen with Aequidens come from two things: dirty water from heavy feeding, and stress from bullying or bad tankmate choices. Fix those and you avoid a lot of headaches.
- Bloat/constipation: fish stops eating, stringy poop, swollen belly. Cut feeding, offer fiber (spirulina/zucchini), check water quality, and raise aeration.
- Hole-in-the-head (HITH) and pitting: often tied to long-term water quality and nutrition. Improve water changes, run fresh carbon occasionally if you like, and diversify diet.
- Ich after new fish: they can get it like anything else. Quarantine new arrivals and do not swing temps wildly.
- Fin damage: usually from fighting. Add cover, remove the aggressor, or separate the pair. Torn fins heal fast in clean water.
- Filter or oxygen issues: warm water plus big cichlids equals lower oxygen. If they are gulping at the surface, add surface agitation immediately.
If a normally bold fish is hiding and breathing hard, do not guess. Test ammonia/nitrite right away. These fish handle a lot, but they do not handle bad nitrogen spikes.
My biggest "success tip" with these is simple: treat them like messy, smart pets. Big filter, steady maintenance, and a tank layout that gives them boundaries. Do that, and they are a really rewarding cichlid to keep.

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.

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.
Allen's river garfish
Zenarchopterus alleni
A poorly known freshwater halfbeak endemic to West Papua (Mamberamo River), described from a single specimen (~13 cm SL). Beyond basic habitat/occurrence, little is published about its ecology or aquarium suitability; assume it is a surface-oriented, jump-prone halfbeak only by analogy with related taxa.
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.
Amatlan chub
Yuriria amatlana
Yuriria amatlana (the Amatlan chub) is a little Mexican native minnow from the Ameca River basin. Its wild range is pretty limited and it is listed as Endangered, so its care info in the aquarium hobby is basically nonexistent and its availability is usually low. In the original species description, preserved fish show a dark lateral stripe with a darker patch on the caudal peduncle, and they can have tiny barbels at the mouth corners.
Andrica moenkhausia
Moenkhausia andrica
Moenkhausia andrica is a little Brazilian characin from the Tapajos system that tops out around 7 cm (about 2.8 inches) standard length. It has a neat netted (reticulated) scale pattern plus a dark spot on the caudal peduncle, and the really wild part is that mature females can have tiny fin hooklets too, which is usually a male-only thing in a lot of characins.
Anhanga pygmy pencil catfish
Potamoglanis anhanga
This is a truly tiny Amazonian trichomycterid catfish - like 1.3 cm max - so it is more of a micro-predator oddball than a typical community catfish. It is the kind of fish that disappears into sand, leaf litter, and plant roots, and you will spend way more time setting up the right micro-habitat than you will actually seeing it.
