I am not sure if anything can hold itself to a clown trigger. Tassled Filefish is a slow grower. I got mine when it was 3" and it is now 5" I have had it 2 years, It is in a 300G. The tassles can not get damaged or the fish will die, they are slow moving, like to eat (should be fed 3-4 times a day) and likes a peaceful tank. My tassled is in a Reef Tank with no problems but I dont think it will ever be able to hold up to a clown trigger.
Look's Like A Butterfly & Stings Like A Bee!!
