Ok I’ve been searching for SO LONG for a post like this. I got a BTA about two months ago. Looked great. Went on vacation over Thanksgiving, and my top off ran dry. House sitter didn’t refill it when she was supposed to. Anyway had a crazy salinity spike and tank crash with subsequent “re cycle” stage with all the uglies. When we first returned home, the anemone was in the ball of death floating around the tank. Clowns still alive, zoas shriveled and melting. I did a major water change and got some new cycled live rock and the anemone uncurled and hid. When it reopened, all its tentacles were gone and it was probably 1/3 the size as usual. Owner at the LRS (he is extremely knowledgeable and has been reefing almost longer than I’ve been alive and that’s a while ) said this can happen when they go into shock from a change in parameters and it can happen in a matter of days, but take six months or more for them to regrow their tentacles, if they ever do. Pic of my naked anemone. It’s starting to get little buds again. I do feed it every week, I just hold the food right in front of the mouth. It looks perfectly healthy other than the tentacles. We did go through a rough patch for a while. I run AI prime so it gets sufficient light. Anyway just thought I’d add to this thread in case it’s helpful for anyone else!
