My 2yo got into Vicks Vapor Rub cream, and put a decent amount into my 30g tank. As soon as I seen what had happened (within 5 mins) I quickly removed all fish into stable water. I cleaned the whole tank with hot water, rinsed the tank repeatedly, also cleaned all the plants, pump, and decorations with hot water. I'm pretty sure I got it all, and I've refilled the tank, added stess enzyme, a new filter, and air rater. The fish are currently in a very small container, I'm wondering if I could put them back in their tank,and what the chances are of fatalities.
