Over the last 3 or 4 days one of my mbuna (a despised yellow lab hybrid) was hiding a lot in a cave and seemed to be turning darker. In fact its head was almost black. Today it emerged enough for me to get a better look, and I noticed that it seems to have a lot of scrapes. I had been worried that it was sick - but now I'm more inclined to think it just came off worse in a fight. Any more experienced fish keepers here have an opinion or advice?
The water parameters haven't changed (hard water, no nitrites, 40ppm nitrates) and the tank is a 450 litre bow front with loads of rockwork and hiding places. The stocking is nuts (fish came with the tank) with 7 yellow labs of varying degrees of hybridisation, 2 rustles, 2 dogtooth, 1 demasoni, 1 jewel, 3 hero efasciatus, 1 blood parrot, 1 synodontis, and 1 black shark. I've had the set up for 5 months and the mbuna have been peaceable enough up to now, with occasional chasing but no serious fighting.
