There is nothing oozing or trailing and the puffer has been acting normal until today. He is not doing anything too strange....just staying at the top of the tank and hanging out.
I have two GSPs which are about 2 inches, 2 small mollies and one other fish that I can't identify.
They are fed primarily frozen blood worms, chunks of prawns and occasionally, snails.
I do a 40 - 50 % water change every 3-4 weeks.
I've had all of the fish for 2 years and the tank has been very stable with no problems to date...other than the second GSP eating a mollie this week!!!
Ammo 0
Nit 0
Nitrate minimal to zero
Ph 7.9
Salinity - .0010
Please help!! Not sure what to medicate with...and please direct me to information on setting up, and maintaining a hospital tank. I'll go and pick one up tomorrow. I've been lucky [and very careful] and have never had a sick fish.
