My anemone is very small right now. When I looked it up it said it was expelling water. This is the first time it has happened in the 2 weeks I've had it. I was wondering what could be stressing it out just in case that was the problem.
Or they just still adjusting to your tank. May take up to couple months. Deflating isn’t a bad thing. Deflating cycle for a ritteri anemone is death. What kind of anemone?
