This thread http://www.myfishtank.net/forum/freshwater-general-discussion/61820-betta-lump-urgent.html has died so I'll ask my question here.

I'm using Maracyn II to treat what I think is an internal parasite. My betta has a lump on her tummy, behind her side fins. It is pink, like the rest of her body except it has a couple white specks on it. I'm thinking that it's parasites, but I'm not totally sure. It would really help if whoever answers this thread reads my previous thread first.
The Maracyn II booklet that came with the medicine says I can use Maracyn II with any other Mardel medicines. Which one should I use? I looked at them at the store and came away feeling very confused. Should I combine with Coppersafe? The bump has gotten a bit red since I noticed it. Maybe it's from her struggling to use the fin on that side.

The medicine treatment will be over tomorrow and she has not improved. I can repeat the dose coupled with another medication, but I'm not sure which one.
