Borneo Suckerfish

What's a Borneo Suckerfish, *please*, surely?

Anyway, manners aside, it's almost certainly a member of the "hillstream loach" family, the Balitoridae. As their name suggests, these fish inhabit fast-flowing streams that are relatively cool, rich in oxygen, and generally low in hardness and nitrates. they feed primarily on green algae (not diatoms or hair algae) and especially on aufwuchs, the small invertebrates (such as rotifers and tiny crustaceans) found in the algae.

Because they need low nitrates, high oxygen, and subtropical water (~ 18 to 22 degrees C) they are singularly ill-adapted to life in the standard community aquarium. Lots of people buy them for tropical tanks, and then are surprised that they die after a few weeks.

On the other hand, you could mix them with white cloud mountain minnows and white-cheeked gobies (Rhinogobius duospilus) in a clean tank with a powerful filter. All these fish require the same conditions, and should do well together.

By the way, Gastromyzon borneensis is a common species and quite likely the species being sold as the Borneo suckerfish, but there are lots of species and telling them apart isn't easy.

Cheers,

PS. There's quite a good article here.
 
I've been keeping two hillstream loaches in 2 tropical tanks for about a year now and they're doing great.

One is quite shy and sticks to glass all the time but the other one is really active and chases all kinds of food i throw in. he eats bloodworms, brineshrimps and shrimp pellets. We've had good luck with them, except those that managed to get out of the tank and those that died when we had a major outbreak last spring that wiped out most of our stock
