Hello! I have an infection going on in my tank. We did a culture and sensitivity on an infected fin of a non-catfish, and came up with Vibrio fluvialis. It's sensitive to most antibiotics, save tetracycline. We have a few options for dosing - water bath, injection, or compounded antibiotic-laced gel food are the ones that come to mind. (I work at a vet hospital, so any option you can think of, we can try.) The issue is getting the medication into my Agamyxis pectinifrons. He doesn't rush to eat at any particular time, so I'm reluctant to dose his food; he might be under-dosed that way. I'd really rather not get cut to pieces attempting injections, but perhaps I could figure it out. Is there a trick do medicating them? I'd prefer not to dose the whole aquarium, but will if I must.

Personally i would use the feeding option & it would always be better to underdose than overdose. Treating the water would be my next choice.

A smaller volume quarantine tank could be set-up with existing water.

Feeding could be accomplished by having a few 'starve days' then feeding a couple of hours after lights out. Add a tablet to the water a minute or two before targetted feeding to get the scent into the water, then you can position the treated food right next to the agamyxis by dropping it down a specifically aimed tube (like a U/G uplift). I have not found agamyxis to be fussy feeders although they can be incredibly light shy. that said some specimens will feed avidly in full illumination after a while.
