Peppermint shrimp never seemed to care before. (I always think they are funnny in that they go wild when I put in some Myces (sp?) shrimp or feed shrimp bits to the anemones (forgot to mention those in the tank, but very far away) - cannibals. Buggers will steal right out of the hands of the frogspawn.

Got them for the aiptasia - don't seem to eat them though. Would the aiptasia be a problem if there's some close that I haven't noticed?

As for the heat or ph, the temp is fairly constant between 76-80 depending on time of day and I admit I haven't checked pH in a while. But wouldn't I expect the xenia to clinch up or not pulse or shrivel?
