Bob, my platy, has suddenly become ill. She (yes she) was fine yesterday, but when I go check on the tank this morning, she is lathargic and had quickly growing white blotches on her fins.
It is a 10 gallon aquarium with a Aqua filter. I just replaced the cartridge the other day.
There are also 2 tertras I just placed in the tank, too though they seem fine.. I keep the water at about 72 degrees F.
Recently. since my last platy died a short while ago, Bob and Skittles, the other platy have been fighting. I'm wondering if it's fin rot from untreated injuries?
So, I need help asap so I can treat my poor Bob.
