my bigest tank right now is a 180gal...i am looking into a 300gal with a 6'x3' footprint...i have a 55gal growout that i have my current fire in and my peacock is in a diff 55gal...i also in the next few years will be constructing a few ponds...
i have found out with some other fish that if you have a few then you have problems, but if you over stock your tank then everyone gets along and you can have some combos that aren't supost to work...one ex. was my african cichlid setup...i had africans, african peacocks, eels, knives, balas, oscars, angels and a few others in the same tank with no problems...reduced the stock to 4 africans and they started killing eachother...
so to make this work i may need a few of each sp..
