Kanabo Badis

Where they come from

Kanabo Badis are from the Brahmaputra basin in northeast India and Bangladesh. Think shaded side streams with leaf litter, root tangles, and gentle flow. The water is usually cool to mild, a bit on the soft side, and tea stained from tannins.

• Shallow, slow tributaries and floodplain pools
• Leaf litter and sand or fine silt bottoms
• Plenty of cover from wood, roots, and overhanging plants

Setting up their tank

They like quiet, structure-heavy setups. A 10-gallon works for a single pair. For a small group, go 20-long or bigger so males can hold separate spots.

• Substrate: fine sand with a sprinkle of leaf litter (catappa, oak, beech).
• Hardscape: small caves and tight nooks. Use coconut shells, stacked slate, small PVC elbows, and twiggy wood.
• Plants: slow growers (Java fern, Anubias, Crypts) and some floaters to dim the light.
• Filtration: sponge or gentle canister return. They dislike blasting flow.
• Cover: a lid helps; they are not manic jumpers, but they can spook.
• Lighting: on the dim side. Floating plants calm them and help shyer fish come out.

Water numbers that have worked well for me: pH 6.2-7.2, GH 2-8 dGH, KH low-moderate, gentle flow, and steady weekly water changes (25-40%).

What to feed them

They are micropredators. Expect them to turn their noses up at dry food at first. Once settled, some individuals take pellets, but plan to start with live and frozen.

• Live: baby brine shrimp, daphnia, mosquito larvae, grindal/white worms, blackworms (go easy on these).
• Frozen: brine shrimp, daphnia, cyclops, mysis. Bloodworms as an occasional treat only.
• Weaning trick: thaw frozen foods with a pinch of fine pellets, then target feed with a pipette. They learn the smell association over a week or two.
• Feed small portions 1-2 times a day. One light fasting day per week helps prevent bloat.

How they behave and who they get along with

They are slow, thoughtful fish. Males posture and color up around caves, but outright damage is rare if the scape has enough sight breaks. They are easy to outcompete at feeding time, so choose tankmates carefully.

• Good fits: small, calm rasboras, ricefish, ember tetras, pencilfish, pygmy Corydoras, kuhli loaches, and small snails.
• Use caution: dwarf shrimp often become snacks, especially babies.
• Avoid: nippy barbs, hyper danios, big gouramis, cichlids, or anything that blasts around and hogs food.

Breeding tips

They are cave spawners with dad doing the guarding and fanning. If the tank is quiet and you feed well, they will often set up a nest on their own.

• Give several cave options: tight entrances are better. Film canisters, small PVC elbows, or slate stacks work.
• Condition with live foods for a week or two. Cooler water change (2-3 F drop) can trigger spawning.
• The male courts and lures the female into the cave. After spawning, remove the female if she is getting chased hard.
• Eggs hatch in a few days. The male usually guards until fry are free swimming.

Fry start tiny. They graze microfilm in leaf litter the first couple of days. Then offer infusoria or paramecium, followed by vinegar eels, and move to baby brine shrimp once they can handle it (around day 5-7).

Common problems to watch for

• Refusing dry food: start with live and frozen, then slowly mix in micro pellets. Target feed so they actually get some.
• Outcompeted at meals: pick gentle tankmates and feed in multiple spots.
• Internal parasites in new arrivals: a pinched belly despite eating is the giveaway. Quarantine and treat with a dewormer if needed.
• Heat stress: above 80 F they get lethargic and infections show up. Keep them cool and well oxygenated.
• Bright, open tanks: they hide and waste away. Add floaters, wood, and caves to make them feel safe.
• Egg fungus or lost spawns: add more caves so pairs can choose better sites and keep the room calm around the tank.
