Ever seen this happen

[marinelife]

I have a ton of Aiptasia in my 120, they cover ever inch of the rock and some are huge, I have tried everything ever listed on this page and never gotten rid of them, the only thing I have not tried is a copperband but I would if I did not have a tang in the tank. My questions is have you ever seen them start to die away. About two months ago I started putting the Bryopsis Algae in the tank and sump that I pulled from my 180. My thinking was if it was over growing everything in my 180 and killing everything then maybe it will kill the aiptasia. Well I thought maybe some good could come of the algae. So it has now been 2 months and the algae is starting to take hold on the rocks, I have noticed the algae on one side of the tank and all the aiptasia are moving to the over side and that the ones that are left look really bad, shrinking, not open full like they were. Could the Bryopsis algae be killing them off. PS the algae in the 180 is still there but under control now, not near as bad, thanks to my Rabbitfish and urchin

I've never seen it but can understand how it happend. After all if anything can overwhelm or out compete one weed its another.

my colt complete drove off the aiptasia on one rock, same thing with my ricordia/hairy mushrooms (still not 100% sure what they are) aiptasia sucks so bad
