Hi all, I just recently lost one of my fish in my 65g tank and I'm now thinking about what fish I should get now. Right now I have a Blue tang, lyretail anthias, 5 blue green chromis, firefish, sixline wrasse, royal gramma, and bar goby. It has been set up for over a year, and this is my first fish loss in over a year also...It was a mandarin who I lost, but idk if I want another mandarin...I'm looking for something probably small, colorful, eye catching, and possibly algae control. Do I have room for a longnose butterfly? Those have always been one of my favorites. other suggestions? I have plenty of swimming space in the tank because the royal gramma, bar goby, firefish, & sixline wrasse all stay near or in the rocks.
