My ebjd has costia and my hospital tank has my Nic(geos tried to evict her) and I'm wondering if it is safe enough to use in my community tank(ebjd, heckelli, rotkeil, sd, common plecos, and mollies)? I have read a lot of reviews of people using it for preventive measures but I've had bad experiences with medicating fish in the past. I also have a 20g with just a mustard gas betta that can be divided if needed but prefer not to go that route.
