You mean synodontus eruptus I think. Unless one of the males is easily excitable and you add viarga to the water. D'OH! I just went there again.

But yes, you get the idea. A firebelly newt is practically the same thing. Smaller, but similar care. They are a great addition to a goldfish tank. I guess I suggested the rough skinned or CA newt because I can find them here and they are considered invasive, so what the heck, I took a chance putting them in a goldfish tank. Found them in a deep permanent drainage ditch one summer. It was great. Worked out fine. They "live long time". Keep the gilled phase in an unheated aquarium and they stay at larval stage for years. Adults can be problematic and prone to escape since they seek land.
