Rick my HMPK recently got a tear in his anal fin, about halfway down.
I believe it was after the water change I did today (50% 2.5g lightly planted sand 1 smooth ornament 2 baby pond snails 1 assassin snail).
He is showing no signs of stress except at night when he is sleeping he has clamped fins. He is active with no signs of finrot. I feed him freeze dried foods switching it up almost every day. Mysis, BloodWorms, Daphina.
His tank is at a constant 78+- 2 noramally sitting around 80, the tank is unfiltered.
Anyways I assume the small tear was from the current from the water change, but what should I keep my eye out for.
There is noting in the tank with sharp edges except maybe the top of the thermometer.
I use a turkey baster to vaccum out his tank.
