Swollen back end on my Dojo

[loachioto]

Hi all,

I was wondering if anyone could help me with one of my Dojo loaches.

Basically, a couple of weeks ago, the back end started to swell up. It also has what looks like some blisters forming. I have 3 other loaches in there which seem fine, and behaviourally, I don't see any change. He is still active, eats food, etc.

I usually do a water change a couple of times a week (30-40% or so)

I have attached some pictures. Any advice would be appreciated.

That swelling could be an internal infection or fluid buildup, so I’d suggest isolating the loach, keeping water quality pristine, and possibly treating with a broad-spectrum antibiotic.
