Right, I understand that but will dosing the tank not do anything at all to the internal parasite? I've been scouring the web for any local place that sells Seachem metro and focus but I have to buy it online and that will probably take a week, so I just went ahead and dosed with the API general cure for a hope it does anything. Also they were sitting in the corner of the tank not getting off the bottom from about 6am to now, been about 1-2 hours since dosing (not saying it has done anything) but they seem a bit more lively now, is them doing a quick circle swim a sign of anything seems like theyre happyish but with my knowledge it could be anything, they also moved to my rock and seem to like that spot.
