Hi mate yes have had quite a few Snakeheads including Dwarf Snakeheads. I have a breed Pair of Channa gaucha they breed easily and are mouth brooders. Channa Orientalis reach a length of about 8", are the dwarf snakeheads as aggressive Compared to the other snakeheads? They are not real aggressive to their species unless they are spawning and I have had them in tanks with all sorts of fish unlike the larger relatives its the old can it fit in its mouth rule. They are a cool fish that can fit into a sensible size tank and you can put other fish with them as long as you think about it before hand like no Neons. Hope this help
