I have a Glo Tetra who definitely has dropsy (pic to come but I’m pretty positive... bloated, pop eyed, “pine coned” scales, etc) and I had one tetra that died about a week ago I had thought it was of old age as it didn't show any signs and was old but now I’m rethinking what might have been the cause... So I did about a 50% wc (this is my 30gal) took off the carbon and put in a first dose of furan2. Now there is 2 Otos and a clown loach in the tank that I’m not sure whether I should move them to be safe or if they are better off getting the treatment doses along with the rest of the tank, or if I should QT the obviously sick tetra into a smaller tank where he can get treatment easier in better quantities because I don’t have to use three packs each dosage and it won’t be as diluted as it will even at equivalent doses most likely... Any ideas on what my next steps might be would be very welcome! He has been moved into a QT that’s 2.5gal as the sole occupant with a bare bottom a fake plant and some free floating real leaves. I am worried that the furan2 I’ve been dosing his tank with isn’t doing enough and I’m not sure if his jaw is messed up and restricting him from getting decent nutrition... should I add something like kanaplex to his med regime or possibly some type of bath? Any advice is helpful. I took a bunch of macro pics to show his jaw issues as well as his overall state. Luckily many of his “pineconed” scales seem like they are back to normal or at least less flared than before and he is less swollen and less pop eyed I think but still not sure he’s gonna make it and definitely not ready to put him back into the community tank. Help? Bottom posts have more info on update... but I’m lost on what to do for him... anyone?
