My largest tinfoil has injured herself - probably by jumpimg and scraping her side on the lid of the 75G tank. The wound appears to be getting infected and the rosy barbs are picking at it (yuck!). I have tried raising the salt level, but don't want to go too much farther, as there are cories in there as well, and they don't tolerate a lot of salt. I have started to cycle a 20G Q-tank and am just looking for some help on medications. I hope to move her later today. I'm thinking maybe some Melafix, and/or some tetracycline? Whatchall think? thx
