yellow lab

My labs got into what i assume was a fight, or maybe a ruthless attack, but i have this lab thats really messed up, pic attached

This is likely a really stupid question, but in the small hours I was thinking about the years I’ve kept Malawi’s successfully (Circa 10 years) I’ve had some minor issues with this batch I’ve started with recently, seemingly an internal parasite issue. I’ve been feeding Thera+ for the past week...

Im looking at getting this set up for my 60g tank that is cycled  Demasoni x12 yellow lab x4 peacock x2   would love some input on this combo
