i,ve had a blue mushroom coral in a week it was ok for 5 days opened up and then yesterday one of the mushrooms died and now the green star polyp hasn't opened???
Yup, sounds like the angelfish's tastes are maturing as it ages . My flame angel when I had it didn't bother anything for a while. A month or two after I had it though it decided to start nipping. It no longer resides in my tank....
Snap same problem I had ive got a cream angenl that loves my polyp have been successful with reducing the amount he goes for it by putting some of this in the tank for the angel to nibble on http/www.onlineaquariumstore.com/acatalo...Sheets_30g.html Angels are natural grazers so are continuosly looking for food, so when there is none there they will go for the corals as its better than going without, that said there is no guarantee it will stop going for the polyp.
