If you dont have zoas File fish has been great. Also heard good things about Australian Stripey. Bherghia have been hit or miss with me. I think my fish eat them or go through the powerheads.
Depends on your tank size but Ive had peppermint shrimps work but I try to remove them afterwards cause they sometimes pick on your corals
Berghia worked in my sump then I thought they died but they made there way into my tank and only come out at night time, I probably have around 6-8 but I doubt theyre going faster than the aiptasia reproducing
When I had a large size stripey he wiped out 90%, he couldnt eat the small ones cause he was too big but he jumped out through my feeding hole
now I got a baby one about the size of a quarter and he hasnt eaten anything yet
Stripey works well , but can be nippy to acans , I got lucky and got one when it was pretty small and it was able to control the aptasia quickly , but also got huge in a span of a couple months . But still doesn’t nip my a acans
Berghia only worked for me when the aiptasia problem was really small. When it was out of control, it didnt seem to do anything. Aiptasia eating file fish work for the display but they won't get the out of reach aiptasia.
Yea idk why either, i’ve always had them periodically. 5-8 would multiply to 30 then they starve and died after all the aptasia are gone. Now im looking for some and fb marketplace have a seller wanting 20-30 each!
