I used to have a clown trigger and a powder blue that were good friends for a few years. The PBT would take the food out of the trigger's mouth.
Just recently I had a yellow tang and a potter's angel that were buddy-buddies. The tang died and when I replaced him, the angel lost interest in friendship. the new tang swims around a lot with a blue hippo and the angel minds its own business.
Beware of them watching TV. My trigger used to like watching tv with me, but it would start acting out the violence!
