My powerheads and filter intakes are all covered. Don't want another milky tank of death...if you know what I mean. What I noticed, is that in the store, it was attached to the glass. It has a red bottom disc, until it is ready to attach itself to something, then it is beige. It has verrucae though. So either it is a Magnificent anemone (highly doubt it), or it is an LTA. It is just cruising around the sand bed. It probably goes around the tank in about 4 hours. Does it every night. Should I get a cup or a PVC pipe with an end cap on it, and fill it with sand so that I can put it near the top of the tank?
