My 55g is sitting empty due to a clown loach disaster so im thinking i'll let it cycle with tap water for a few weeks just to make sure its clean and start a catfish tank. I want a Redtail cat, o. niger, TSN and maybe a perruno but i think i'll settle for a lima, albino channel cat and 2-3 others. (i have a pond for the channel cat, i want to grow it out before he goes in the pond). As for the lima, he'll need 2-3 friends but i dont know what. I need some help picking out odd and unusual cats to go with him. I can move them to the 150 when they out grow the 55 so anything 12" and under is what im looking for and please dont suggest pictus, rapheals, sun cats or plecos.
