I've seen shrooms do all kinds of odd things, sometimes irritated, sometimes on the move and sometimes letting go (irritatingwhen this happens). Like was already said, keep an eye on it and I'd also watch that crab! Nice shroom, btw!
The crab settled few days ago on mushroom.
he is grifting. About 2-3 weeks ago we lost our anemone in wave maker.
at first he was sitting exactly where his anemone died and now is just moving around.
thank you
