Hey folks, my RTB split over a month ago, small guy didn't make it but the larger split did and was doing fine attached to a big rock flowing all day long and disappearing at night into the rock. About a week ago when I got home from work he had he dislodged himself and was lying mouth down in the sand bed. I place him (or her) in a plastic isolation container and left him in my tank. For the past week he has been shrinking down to the size of a half dollar at night and expanding 6"-8" during the day, but not looking healthy. Mouth open for a good part of the day. Clowns were very active wit hi prior to the dislodge. Water parameters are good, phosphates just slightly high. Any suggestions?
