I have a baby tiger clam on hold for a couple of days, but before adding it, who in my tank am i going to have to KO or watch out for when I add him?..... I have a coral banded that always looks guilty, never know with him, anyone know about any problems?... I'd also like to put him on the sandbed, mostly because I don't want him to fall when he's newly added. But in that, I also have two engineer gobbies, they love to push sand out all over anything on the ground and are constanly rearranging the floor to their liking... any suggestions????? Also I've always heard of green legged hermits rampaging tanks, coral, and other friends... but what about blue? I have many, and they seem to be very nosey, but mostly just stomp things and move on.... Any problems with these guys or dove snails??? I've seen a lot of post also conscerning cleaner shrimp, I have three of those and a fire shrimp... I want our new little guy to be happy in his new home, so any feedback would be much appreciated...
