I spent a lot of time this afternoon looking into and a little Melafix and a tiny bit of salt is fine for plecos. The mollies are smaller ones who are moving into a twenty gallon within the next day. As for sharp objects, there are none in the tank. I made sure everything was smooth before I placed them into the tank. The pleco is not even three inches long currently, its a smaller one.
I was just wondering if there was something else out there besides melafix to treat wounds.
