Please help ID, not sure if peaceful or harmful to tank. Have a single base like a anemone, Here is what it looks like when open up and recently closed when my red hermit wondered beside it.
Thanks in advance. Sorry for poor picture quality taken when all lights off.
Check the kh with salifert blue doesn't change color at all. this means my alkalinity is over 15 dkh. I turn of CR and will change about 20% today hope to get everything back slowly.
