I also have a 55 gal aggresive tank that I am setting up.
I have 65 pounds of live rock,
a amazing young 3 inch darf zebra lion
flame hawk fish
ocellaris clown (adopted when my nieghbor took down his tank)
2 yellow tailed damsel (used for cycling)
various shrimp, crabs, and snails
My question was would it be alright to add a small 2" humu trigger to the mix or would that be overstocking it. My damsels are expendable and I can find a new home for the clown if need be. I plan on upgrading to a 180, but not till after this next year of college. Also, some say that the triggers nip at the lion fishes fins. I love the personalities of the triggers and would love to add one to my tank, but not if I will be really overstocking it or harming my lion.
