Is the smell of Pimafix and Melafix bad for Tiny? Right now I’m treating my fish for fungus and fin rot. And from what I know they contain essential oils.

Melafix contains tea tree oil. Pimafix contains Bay Rum oil. Both can be toxic to dogs, however at the concentration used this is unlikely. Tiny would need to chew up and drink the contents to be at risk of toxicity. Normal use in the tank is safe for him. Keep the bottles out of his reach.
