Any fishkeepers here? Saltwater or freshwater

Treating aeromonas in tank is an option, since alot of the medications used to treat it will not destroy your nitrifying bacteria. However, given your water parameters and issues you're having, I wouldn't add ANYTHING to your tank other than maybe a bit of aquarium salt.

One other thing - aeromonas is an anaerobic bacteria. Increasing oxygen levels can be a big help. If you don't already have an air stone running, run one. If you have an air pump that can handle it, run 2 or even 3.

From what I read about aquarium salt, tetras don't respond well to it, so I haven't done that yet.

Also, the bettas swelling is completely gone this afternoon, and he's no longer hanging out doing nothing on the bottom of the tank. He's back to being alert and active, swimming all over the place and eating. WTF? His belly was swollen and he looked like a pinecone this morning. Did his belly explode? LOL
