My daughter has a 5 gallon tank with filter (the type that sticks on the side, had carbon and floss). We put in 1 baby Oranda goldfish and 3 white clouds, changed about 30% of the water 1/week while vacuuming and were careful to not overfeed. Goldie got sick (floating on top, tail hanging, no sign of anything else), finally died. Now I wasn to disinfect prior to putting in new goldfish, how do I do that? I will change tht filter but what about the tank itself, can I use bleach?
p.s. I know we will need a larger tank whent he golfish goes over an inch..
