Aiptasia and Butterfly Fish

[win]

ive had a copperband in my 75gal and it did a great job of eating aptasia
but he also ate my feather dusters. and he grew very large even though i bought him as a juvenille.
I dont believe the myth" a fish will only grow to the size of its encloure"
try peppermints i haev since replaced my copperband with a few of these critters and they have done just a good job!
