This may be a long shot but I'm at a loss as to what is going on with my one acrylic tank.
It's been set up for 4 months and over that time I've had a few RCS, a couple platys and a number of guppies all either disappear or die.
At first I had ick run through the tank which I treated with increased salinity and heat which seemed to work well although I did loose 3 guppies to ick.
Ever since then (2 months) it has leveled out, the parameters are stable and my plants seem to be doing well but every so often I seem to either loose a guppy or I find one dead. They exhibit no symptoms leading up to the death. I decided to transfer my one female and her fry to a separate tank and they seem to be doing well. The fish were healthy from the pet store when I got them but I thought I would get a few from a breeder in the hopes of having a healthier fish but they also died.
Has anyone heard of acrylic tanks having any effect on fish health? Any help is much appreciated as it is now I'm thinking of taking it down and getting rid of it.
Cheers.
