I recently took in a freshwater tank with one pleco and 27 guppies in it. When I picked it up, the water quality was atrocious....it wasn't full, and the water itself was a carmel-brown color. Needless to say, the guppies were all nearly colorless when I got them.
I've had the tank completely cleaned, and it's been up and running with the fish for about 2 weeks now. The guppies have all gained a tremendous amount of color back, and none have died since the initial transportation.
My problem is this:
some of the fish have fin rot, and there are several who are deformed. I thought at first that the deformed fish were just the result of growing up in a bad tank. However, I'm now led to believe that they have developed fish tuberculosis!!
Given the fact that my tank is already a bit heavily stocked, and both of these diseases can be fatal, should I just remove the fish with TB in order to save the rest of the aquarium instead of trying to treat the whole tank? I don't have the space to set up another "treatment tank", so if I treat one, I treat them all.
Do I cull the infected fish or no?
it is a 25 gallon...which is why i'm seriously considering just taking a few out.
again, I don't have space for another tank!
the pleco is actually rather healthy! he was a little lethargic at first, but some algea tablets and greenery have really got him going lol
