Last week we bought a squamosa. Day before yesterday, I put him in tank water with DT's. Set for about 10 min. Returned him to sand bed. Yesterday he was beautiful!!!! Today, drawn in. And just now, a peppermint shrimp was eating him. What in the world went wrong. I honostly dont think it was sick to start with??? I did a lot of water flow changing of directions this am.(wavemaker was only working on one side)What would be in my water that could kill him? I mean, what should I do tests for? All parameters SEEM fine. I am not sad about the $$$, its that it was a living and beautiful creature and I killed it
