I was moving stuff around with my hands in my quarantine tank with a clownfish that has some sort of parasites. There is also medication in the water (Ich X to be exact). I wiped my hands off on my pants and paper towels and about 15-30 minutes passed before I accidentally put my fingertips in my display tank. It was just my fingertips and they were in there for less than half a minute, possibly less than 1/3 of a minute. I’m a bit paranoid and worrying if I potentially introduced any medications or parasites into my display tank. I have a goby and blenny in there right now that are still fine and dandy. I took the clownfish out last Friday and my lfs told me that if the goby and blenny dont show any signs till this weekend that I’m probably in the clear. I’m just really hoping I didn’t screw that up with my stupidity.
