Hello people, how is everyone doing? My question starts by me having a 55 gallon fish tank. Istarted out with 3 convict(striped), 2 of them joined and killed the 3rd. Well that is only the half of it. Now I have at least 15,maybe more convicts in my tank along with 2 jacks,2 oscars and 2 other african cichlids. Is it too much to ask whether they will all survive one another or will everything go along smooth. They do fight some,the oscars and one of the other african cichlids. Please help

Wow. I've seen Oscars alone eat every other fish in the tank they were in. With such aggressive fish, if it were me I would separate some of them. This will make them live longer happy lives :)
