Hey,
I have kept quite a few dwarf channa in the past. Bleheri are definitely pretty cool and great for their price. They have some of the better colors for the more common dwarf snake heads and become very personable very quickly. They will spend a lot of their time just hanging out in front of the tank waiting for food haha.
They are pretty easy to breed too. I just kept mine in a very well planted 75 gallon with 6 individuals (just a ton of java fern and moss) and then just had them on a lighting cycle. Nothing scientific, I was only trying to breed them for fun. I'm pretty sure I just changed the temperatures a few degrees every month (lower towards winter and higher towards summer) and then just timed the lighting to go along with the changing temperatures (longer nights in winter, longer days in summer, pretty simple stuff). I also have always figured that in the summer months water levels went down naturally so I gradually let the water levels in the tank go down with the warmer season.
Other than that I just kept them well fed, but not fat. I fed mine just about everything, color enhancing pellets, cichlid pellets, massivore sticks, blood worms, krill, shrimp, live food. Foods like blood worms, krill and shrimp will really bring out their colors. It's always good to have a bit of water flow so they get some more excercise than just floating in still water.
Good Luck,
Justin Morash
