My yellow tang and flame wrasse have developed a great friendship and bonding between each other.
They follow each other about tank. "Hang out" together under large toadstool. And frequently bump and rub up against each other when out wandering about. (no the tang does not try to swipe the flame).
Is quite an interesting relationship. Both have generally very peaceful and docile dispositions, and up to now have been mostly solitary fish. Always come to front of tank together when any activity in outer room, esp when they know it is feeding time...the flame is always "showing off/flashing" his colors when he is in company of tang. (I think to show he likes him)...
Have no idea what attracts them to each other. Very different in shape and body color. I guess fish can make friends with those of another color, just like people can.
