I currently have a 55 gallon tank with 1 jack dempsey 1 green terror 1 jag 1 turquoise serevum and 1 gold nugget pleco I am getting a 75 gallon. I was wondering if I could house all of them in the 75 Gallon? They are all about two inches now. I was debating on splitting them up any suggestions? I would like to make all of them a permanent home together and get some dwarf american cichlids to put in the 55 gallon. But I want them to have enough room.
