My alpha male convict cichlid is extremely lethargic, he is leaning up against a rock at the bottom of the aquarium and he has a few whitish sores on his lips (only on his lips) and some of his anal fin is missing. He has been doing this for about a day now. Him and another female were protecting fry so I think that explains the fin damage, but the spots and lack of movement puzzle me. Everyone else in the tank 80 juveniles and 3 adults all seem fine.
125 gallon tank
0

0

Temp is 78 F
This is an extremely stable tank and the parameters have been the same for many months.
I have moved the male to a 29 gallon hospital tank and dosed him with quick cure. Any other suggestions or ideas? I do NOT want to lose him.
