I am so overwhelmed and devastated. I am having a velvet outbreak with my bettas....not really sure how it has spread as I previously only had one infected fish. I'm thinking maybe the hose I use to clean tank. Only one fish has the gold dust but now I can see the little critters swimming in my other tanks. I have had my other tank covered with a black trash bag to eliminate light and have been dosing with general cute for parasites but have seen zero improvement with my fish or even reduction in the critters in the tank. So my questions I guess are: What is the most effective form of treatment? Do I remove the snails and treat the bettas in their tanks or put them in quarantine bowls (I don't have 3 spare tanks/filters around for proper quarantine) if in bowls how do I rid the parasites from the tanks? Would a UV filter do the trick in ridding the tank? I have never dealt with anything like velvet....this is a nightmare.
