Hey guys, I just bought a standard 48" 55g tank for my classroom at my new teaching job where I will be teaching a Marine Biology class. I already have a 29G set aside for a planted apisto breeding tank (to teach life cycle) and in my 55G I'm looking for some bigger colorful fish that I dont want to have to plant the tank. I've kept Labs 1M:3F , Red Zebra 1M: 3F, and Demonsoni before and have bread Labs and the Zebras (the demonsoni was a sole male). I'm really wanting to do peacocks either A) 1M:2-3F Dragons Blood and 1M:2-3F OB (I know both are hybrids and many people have issues with that but I find the colors stunning) for 8-10 fish all in the 4-6" range. Both these breads are suppose to be easy to sex as Juvies with the females not having the bright colors or B) 6-8 All male peacocks which my LFS has a special tank reserved for only males at about 3" a fish. I'd like to avoid Mbuna if possible as I've already done that once.
