About 2 weeks ago I bought a blue dwarf gourami from a pet store chain and introduced it to my established 20 gal that contains 5 cherry barbs and some plants. All seemed to be going well -- everyone was eating, no bickering. Last week, though, I noted a little bump under the gourami's mouth. I decided to watch it for a little before taking action. Around Friday, though, the lump seemed to have ruptured and turned into a nasty little pinkish sore! I started dosing the tank with Melafix on Saturday but the sore doesn't seem to have changed much except now the scales are starting to flake off.
What's going on and what should I do? I'm thinking it's some kind of bacterial infection but I'm not sure if the Melafix is working, if I should find another medicine, or if I should euthanize the fish (it doesn't seem to be in pain...yet). The gourami is still eating well, but it doesnt seem to want any of the medicated fish food (Jungle brand) but neither do the others
Here's the gourami around Saturday
And here it is Monday (today)
I know it looks worse but in reality it's hardly changed except for the flaking
