Angels are cool wife has a 55 with them in. we also have a pair of west african pelv. taen. moliwe. there also with a pair of zamora woodcats. and have had no problems for almost 4 months but i am predicting a bit soon. the pelv. are showing signs they are getting ready to pair up. lots of quivering going on. tetras, cories, and umm drawing blank here, would be a good addition to the tank also. look up where the angels are from and do a biotope with other fish that live in the region. 1 of the cichlid sites i visit has a coockie cutter formula that puts fish in that goes with them. cichlid-forum.com give it a try and see what it gives you. might be all cichilds though been awhile since i used it... oh and plecos of all kinds would be good
