I fed my anemone a piece of shrimp and it was too big I guess cause it spit it out and I didn’t notice and it was sitting there for a few days and it looked just like that so I picked it up and it went away. Did you try and feed anything and leave it there on accident?
No, I feed either mysis shrimp or pellets. It’s just on and around this one frag. The rest of the tank is fine. The foam has been there for like a week. Hasn’t changed. The frag has been there like 2 months.
