As many know I have a 625g (7 1/2 ft long) FOWLR that has mostly tangs and angels (large and dwarf). Also has 4 ocellaris.maroon and orange diamond gobies in there as well. I’ve been torn about adding a clown trigger. If I add a 2 1/2-3 1/2 inch, how fast will it grow? Does it really reach 20 inches in captivity? At what point, if ever, will it be a threat to the smaller inhabitants if it grows along with them? Thx to all for opinions and especially from those that have experience with this beautiful but aggressive trigger.
