The female from the apisto's died fairly quickly, the male lived about two years and was a pretty cool fish.
Not too territorial and he left most of the other fishes alone. But he didn't like dried or pellet food, live or frozen food only.
I'm not sure of it's English name, could be leopard fish, it's scientific name is ctenopoma acutirostre.
I had two of them and they were about 4 to 5 inches and after doing some research I found out they can reach about 8 inches.
Anyways, the ctenopoma's and the 2 butterfly fish moved to a friend's tank wich is much bigger than mine.
And started of with some smaller fishes in my new setup of this tank such as Iriatherina Werneri; stiphodon percnopterygionus; corydoras pygmaeus; endler guppies and shrimps.
