At work we have this 37gal tank. It is set up for goldfish-- heater set for 70 degrees. PH at 6.5 and cycled last year.
Every time we put a goldfish in (fancy Orandas) the fish get sick and dies within 1-2 weeks!!! Looks like velvet but not sure. I have never fought this problem before!! I have kept fish for over 50years W/O this kind of problem.
Starts of with loseing color (red parts getting lighter). Tails looks like been dusted with a fine white dust. Fish starts to float--4 days later ==gone!!!
It is not ick. There is no ammonia nor Nitrite. Snails are fine in tank for over six months.
I have done lots of WC==no help. Have left tank empty for 2-3 weeks==no help.
Thinking of taking all inverts out and triple-medicate with copper for 2-3 weeks and restarting.
Any ideas???
