In my tank I have a rainbow and albino rainbow the normal rainbow is smaller and I find they dont bicker if the temp is a bit colder mines 22-24, a few caves so there not in constant visian , well fed and clean water. I personaly wouldnt get a red tail with an albino because the red tails can be nuts and the albino IMO is a bit weaker or dopier than the red tail and rainbow, hope this helps.
