My betta has ick so I put a drop of aquarisol in the water to try to help clear it up. But after doing that, I noticed that the aquarisol label says it's harmful to snails. Should I remove my snails?
If it says harmfull to snails then it probably contains some form of copper.
It's probably best to remove the snails until you've stopped medication.
What other fish are in the tank with the betta? Copper can be harmful to some fish too, and shrimp.
