About the Giraffe catfish
A huge African catfish with a giraffe-like pattern as a juvenile that tends to fade as it matures. It digs through sand with long barbels, males guard nests, and in the wild they can even end up hosting another catfishs eggs. Give it lots of floor space and tankmates too big to swallow.

Calculate heater sizeCare Notes
- Plan for a 70 cm fish; an adult needs at least 200 gallons with a long, open footprint and lots of floor space.
- Use fine sand as the substrate; they constantly dig with long barbels, and coarse gravel can wear or injure them.
- Anchor heavy rocks and wood securely and do not rely on delicate rooted plants; this species will uproot and rearrange decor, so use plants attached to hardscape.
- Keep temperature at 21-25 C and pH between 6.5-7.8. Run strong filtration and keep the bottom clean because this big digger produces a lot of waste.
- Feed a varied sinking diet: quality pellets plus worms, crustaceans, and mollusks; they will eat small fish, so do not mix with anything bite-sized.
- Tankmates should be robust and too large to swallow; give plenty of room and line-of-sight breaks to limit scuffles from their semi-aggressive nature.
- Expect the giraffe-like juvenile pattern to fade as the fish matures.
- Breeding in home aquaria is rarely reported; in nature males guard nests, and they can even end up hosting another catfish's eggs.
Compatibility
Good Tankmates
- Adult bala sharks or tinfoil barbs 25-35 cm - fast midwater fish that are too large to be swallowed
- Very large, deep-bodied cichlids 25 cm+ that are not hyper-aggressive (e.g., oscars, big tilapia) - robust enough to coexist
- Big Polypterus bichirs 30 cm+ - armored, non-nippy, and generally tolerant if the tank has multiple hides
- African arowana (Heterotis niloticus) or similar large, peaceful surface cruisers - occupy the top and ignore bottom activity
- Adult Synodontis catfish 20 cm+ - spiny and tough; can share the bottom in a very large, well-structured tank
- Large Distichodus species 30 cm+ - fast, deep-bodied characins that are hard to swallow and handle the activity level
Avoid
- Anything small or slender enough to fit in its mouth (tetras, danios, livebearers, small barbs) - will be eaten
- Delicate or slow bottom dwellers it will bulldoze or outcompete (corydoras, kuhli loaches, small plecos)
- Shrimp, snails, and crayfish - treated as food
- Very aggressive bruisers and fin-biters that escalate fights or stress it (rock-dwelling Rift Lake cichlids, large Clarias, snakeheads)
Giraffe catfish (Auchenoglanis occidentalis) are huge African bottom diggers with long barbels and a juvenile pattern that looks like a giraffe and usually fades with age. They can reach about 70 cm standard length, live 10-20 years, and are best left to aquarists with space and experience. This is a semi-aggressive, opportunistic omnivore that needs a very large footprint and tankmates too big to swallow.
Minimum tank size: 200 US gallons. Water: freshwater, 21-25 C, pH 6.5-7.8. Care level: advanced.
Origin and natural habitat
Native to Africa, this species inhabits freshwater systems where it forages over sandy or muddy bottoms. The long barbels are used to probe and sift the substrate for invertebrates and other food. In the wild, males guard nests, and their nests can even end up hosting another catfish's eggs.
Aquarium setup and water conditions
Prioritize floor space. A 200-gallon tank is the minimum, and longer footprints are far better than tall, narrow tanks. Use fine sand as the substrate so the fish can dig safely without damaging its barbels. Coarse gravel is a bad fit here.
- Substrate: fine sand for safe digging and natural feeding behavior
- Decor: large, smooth rocks, sturdy wood, and roomy caves; place items securely as this fish will undermine them while sifting
- Plants: expect uprooting; use tough, well-anchored or potted specimens if you try plants at all
- Filtration: high-capacity, reliable filtration and strong aeration to cope with a large, messy fish; keep intakes guarded so they do not ingest sand
- Water: 21-25 C, pH 6.5-7.8; keep parameters stable with frequent water changes
Barbel erosion happens on rough substrates and in poor water quality. Keep the sand clean and smooth, and maintain excellent filtration.
Feeding
An opportunistic omnivore that feeds on the bottom. Offer substantial sinking foods and vary the diet.
- Staples: large-quality sinking pellets for carnivores/omnivores
- Meaty items: worms, crustaceans, and mollusks (for example earthworms, shrimp pieces, mussel)
- Feeding pattern: scatter food over the sand; evening feedings work well as they become more active then
They will eat small fish. Choose tankmates that are too deep-bodied or large to fit in the giraffe catfish's mouth.
Behavior and tankmates
Semi-aggressive more by size and appetite than by constant hostility. They are powerful, boisterous diggers that root through the substrate and can jostle slower fish. Most aggression shows up around food or floor space.
- Best kept with other large, robust fish that are too large to be swallowed
- Avoid small or delicate species that spend time on the bottom
- House one per tank in typical home aquaria; adults can be territorial with similar bottom-dwellers
Common problems and how to avoid them
- Outgrowing the tank: plan for the adult size before you buy; they can reach 70 cm SL and live 10-20 years
- Swallowed tankmates: select only large, non-bite-size companions
- Barbel damage: use fine sand and keep it clean; avoid sharp decor
- Toppled aquascapes: secure rocks and wood; they dig and undercut structures
- Water quality swings: this is a heavy feeder with a heavy bioload; use strong filtration and regular, large water changes

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.
