Hi! I have a 20 gallon planted tank with a school of rasbora hets, a female betta, and a mystery snail. This tank is well established, coming up on its one year anniversary. I have had the rasboras since Christmas time. Anyway, just recently I noticed one of the rasboras was not schooling with the others, which I thought was odd, so I looked closer and I saw redness and swelling around one of the gills. The abdomen appears to be slightly swollen as well. Pics attached. Any idea what I’m dealing with here? Thanks in advance.

Hello! :)

Thank you for the clear pictures! :)

It could be a wound from another fish, what other species does the HR live with? :)
 
It has inflamed gills. Do 70% water changes, clean the subsrate twice a week. [This is Collin_t's advice, Trying to be like him] Lol:):)
 
It looks like a bacterial infection, there is red on the side of the body as well as the gill cover, which appears swollen.

Try doing a 75% water change and gravel clean each day for a week. Make sure any new water is free of chlorine/ chloramine before it's added to the tank.

Clean the filter if it hasn't been done in the last 2 weeks. Wash filter media in a bucket of tank water.

Check the ammonia, nitrite, nitrate and pH of the water. Post results (in numbers) here.

If the water is good and there is 0 ammonia and 0 nitrite, and less than 20ppm of nitrate, and there has been no improvement after cleaning the filter and doing a couple of big water changes, then look for a broad spectrum fish medication and treat the fish in a quarantine tank if you have one. If you don't have a quarantine tank then just treat the main tank.
