Here is the description of the antibiotic food I've been using:
Anti-Bacteria contains sodium sulfathiazole and nitrofurazone to help control internal bacterial infections as well as external infection, open sores, ulcers, columnaris and fin rot.
I've used melafix in the tank. Removed carbon filtration, used for 7 days, followed dosage on package.
Tank doesn't smell like rotten eggs or sulfer.
Should I try a stronger antibiotic?
Is it possible that the zebras, cat and pleco are hardier fish and this is why it doesn't bother them?
Thanks for all your help,
Jessica
It sounds like to me that something is wrong with your water quality. Have you gotten any cleaning products near your tank?. Did you wash your hands before you put them in the tank. Fish from bacterial infections don't die that fast. You probably had one to begin with then with all the meds you put in the tank I am sure you killed it. Alot of med's kill the good bacteria too. I don't usually do a 30% water change weekly. More like 15% or 30% every other week. I think you need a recycling. I use biospira and special blend. It sure sounds like your fish don't agree on your water. I am so sorry your fish died. I had the same problem a few months ago.I know how frustrating it can be. I transferred my fish to another tank and did a complete recycle of my tank. I hope your problems clear up.Wilder, thanks I'll try that. Maybe I can save this one. Is there anything else I can do to make sure this doesn't happen next time I get more fish? (besides quarantine and keeping up with the water changes)
