So I have a Coral Beauty that is a Survivor...All My Fish Died from Brook and the Angel Survived. Hasn't touched any Coral. I have Acros, LPS, Acans, Mushrooms, Zooanthids, Etc. I Know Potentially Dangerous to add a Maxima Clam. LFS has a Cool Maxima about 2" for $90. Guys there Said Introducing a Clam Might Cause the Beauty to Eat the Clam and then Cause appetite for Other Corals that hasn't touched B4. Im ok with losing the Clam but Definately don't want it going crazy and killing everything else! Also the Tank is a 20 gallon Long So Kinda Small maybe makes a difference...Any Help and Advise is MUCH Appreciated! I REALLY Want this Clam but I don't want to Lose $90 especially More. Peace.
