Hemiodontichthys acipenserinus advice

[philippe31]

I I will have a group of 7 Hemiodontichthys acipenserinus in January and I will like to have some advices about these fishes.
I read several things on Internet, and seen video on youtube. I am a bit affraid by the low activity of these fishes, so I planned to put them alone in a tank, but can someone tell me what is the better size of tank for them? Is 100*40cm a good size?
Thanks for help

I had a pair of these (captive bred) and to be honest they gradually deteriorated. I think I should have had them in a tank of their own with more optimised conditions. For a group of 7 I think a slightly larger tank might be a good idea. Mine were actually quite active on the bottom; they ‘walk’ rather than swim.
I think they need very clean fine sand and a reasonable water flow.
Hopefully someone else with better experience can help.

Hi Philippe31, Hemiodontichtys are indeed very slow fish. They walk like chameleons but can shoot away like lightning when trying to flee. They need a nice sandy bottom and some shaded area's, from (overhanging) wood for instance. They are indeed very sensitive to water conditions and don't do well with high levels of stress. Stress can come from other fish in the tank, so choose wisely. No Tetra's and no fish that are (food) aggressive, if you give them tank mates make sure they are suitable.
I keep mine in a 1.00-50-35 tank. I own a breeding group of about 8 adults and I can't count the number of fry that there is in the tank, they are everywhere I feed them Repashy at night and for the fry I feed some de-capsuled Brine shrimp eggs in the morning as an extra.

Thanks Mol_PMB, I have read they are difficult, I hope I will have more luck than you
Thanks jac, so the tank I will use will be near the same as yours. I will keep them alone to begin. Very nice pics and very good job with fry!
Can you be more clear on what kind of Repashy you use? It seems there is several products with this name and I known none (I use Tetra discus for most of my canivore fishes)
