My mistake i have the trimaculatus and flavisima dwarfangels, they do the same as the butterflies. They swim around and peck on corals.Sorry, butterflies, as in butterflyfish? He asked about your flagfin angel. Do you mean angelfish? I have a regal angel myself. He hasn’t touched my corals yet, but I’m getting worried…
Because of their small size the were able to swim to section1 which contains al LPS like acan's, lobo's, trachy's and zoanthids i saw them do doing considerable damage to them and the polyps were retracted al the time. I lure then to section2 and placed a unmodified eggcrate inbetween so they can't swim back.
Sps in section 2/3 are just fine. These corals can handle the pecking providing they are abundant and healthy.
