Thanks for the replies. I think I will start on fixing his diet, monitor the water quality, and also add one of 2 tiny cleaner shrimps to it.
I picked up some dry seaweed sheets, cut them up in small pieces, stuck a piece between 2 of the rocks, however he doesn't seem to be interested at all. Is that normal? I mean, eventually he'll go for it? Or they should be craving for it?
Right now, i have the LR
in the middle, stacked with holes just so the fishes can swim from the front to the back of the tank. I am thinking of pushing all the LR
to the back of the tank (of course with some holes for them to hide), thus creating more spaces for them for now, until I have my new bigger tank ready. Would that be a good idea? or it would create more stress?
