And the chaca chaca grows to about 8 inches, and is also very sedentary. They are both ambush predators that rarely move except with feeding. Both species are recommended for species tanks because they either eat their tankmates or get outcompeted for food by them, but in theory they could work quite well together, as far as I can see. Their needs are quite similar. The main worry afaik would be that the chaca would try to eat the prehistoric monster fish, but I don't that is very likely.
