Rasbora With Redness And Swelling

[IHaveADogToo]

I have a school of rasbora hets with a female betta and a mystery snail in a 20 gallon planted tank. I noticed one of my rasboras wasn’t schooling with the others and when I looked closer I saw redness and swelling around the gill and also the abdomen looks a little swollen as well. Pics attached. Any idea what I’m dealing with here? I should note this tank has been established for nearly a year. I’ve had the rasboras since Christmas time.

That looks like it might be septicemia it’s treatable but it takes commitment I lost a few fish to it while treating my tank Its basically a blood infection it’s pretty contagious so I would treat the whole tank. If possible treat immediately

After googling septicemia I think you’re right. I lost a rasbora a couple of weeks ago. They didn’t show redness or localized swelling like this one is, but the abdomen did look bloated. So this pattern of events fits the bill. I had already added some E.M Erthromycin to the tank earlier today, thinking this was probably some sort of bacterial thing, and it looks like my hunch was right. It also looks like I’m going to need a different med, though. I’ll drop by the pet store on my way home from work tomorrow. What meds do you recommend?

I think I tried bacterial treatments like melafix but it wasn’t working well I had to go to a pet store and specially request a semI powerful antibiotic. They probably won’t have it at any of the big box stores like petco and petsmart. So it might be a little out of your way to find a mom and pop shop. Most antibiotics will probably work but I would ask someone who works there for advice on which one use as all small stores don’t carry them all either. I can’t remember which one I used but I just hope you’re tank isn’t too big because you have to do daily water changes it was borderline torture treating my 55 gallon with a 1 gallon bucket. If the first round doesn’t work try going back for more it took my fish two rounds to recover. It’s also highly contagious so I wouldn’t move them to a hospital tank and treat their whole tank. The people at the store should tell you how to use the antibiotic but if you have any questions just google it as it every antibiotic is different. Septicemia works fast so I would treat it asap. There is an untreatable viral form but it sounds like yours is the bacterial because it appeared suddenly. Water quality is a big factor so try changing the water too.
