Thanks Charles, 12 in a 90Gal right now(plus a 20gal sump). about 5gal water change a day(skip a day or 2 in there sometimes) usually Ro mixing in 2gal Tap thats been de chlorinated between to keep some trace minerals. Just setup another tank (90gal Bow) That i will be dividing these up into. I would think they could go with Normal Angels, They are a bit pushy with each other at times but generally good i think they like schooling together but want to give them more room for sure.
