It doesn’t say on the bottle, just how to treat.I have never used it, so don't know, but i usually suggest to start with the directions on the package or manufacturer' website, if possible, when it comes to any meds. Do you have access to either of those?
Both fish did well, though I would say the danio was a bit stressed. Maybe I’ll do every other day for it. The betta acted normal.When I use MB baths, the frequency I give the baths depends on the stress level of the fish. If they are ok with the bath, I will do one daily for about four days, and then give a break. If they are stressed, then every other day. If they didn't take well to it at all, then I move on to a different treatment.
