In my 65g FOWLR
tank, I have a snowflake eel, brittle star, serpent star, tomato clown, 4 turbo snails, red volitan lion, niger trigger, humu trigger, coral beauty, sand sifting star, royal blue sand sifting star and a strawberry crab, all introduced in that order. I have not had 1 issue with any of them not getting along in any way. Maybe that's just the personalities of my fish, don't know. I realize that when these fish are full grown, 65g is not going to be enough tank. I was well aware of this when I started it, and fully plan on upgrading to a 180 when that time comes. I don't know if this helps any, just thought I would share my experience.
