Hello. I have a 45 gallon tank tank with 2 clown loaches, 5 cardinal tetras, 2 swordtails, 2 corys, 6 zebra danios, 2 pearl gouramis and 2 gold gouramis and all fish are compatible. None have reached adult size and will move to a larger tank later. I would like to add 1-2 yellow cichlids, 1-2 angels and a severum. Any advice on compatibility to my existing fishes? Thanks.
