Yesterday is want to put some corals in my tank and i say a strange thing between the rocks.. it was my biggest GSP!
He eats just like normal, but he is not as hyper as normal. The smallest GSP doesn't leave the biggest one and it looks like the smallest, Muppet, want to take care of Mini the biggest.
On a other forum it is thought that it has to do with dominance, but Mini is the boss... not Muppet, so I can not imagine that that is the reason!
Also it looks like Mini has diarrhea..
Littlte thing that i've done the last weeks. I removed the big pump and placed 2 flow pumps in the tank. The NO2, NO3, PO4 en CA are fine... only the NO3 is a little bit higher as it should be, but that is normal.
PH and KH i can't measure..
Does anybody has a idea what is wrong with Mini? I dont want that anything happens t him..
