Hello, I currently have a 10 gallon tank that is, in my opinion, heavily planted (with gravel), with driftwood, a filter, a heater (not in use at the moment), and a hood light with a day/night function. The current occupants in this tank are around 10-15 small snails, 1 huge snail (I don't know their species), a random shrimp that I never bought, a Rhino Pleco, and two swordtails. (One male and female).
The problem is, my female swordtail (who has a tendency of getting pregnant, I have seen fry in the tank before, but it was probably eaten), has a clearish bubble like space in her head/backbone. People I have previously asked say it may be an air pocket, gas bubble disease, cancer, or a tumor. Symptoms of what I think may be this bubble or her pregnancy include staying near the filter, and generally the surface of the water, and spitting out food, which she has been doing for nearly 9 days now. The strangest thing is, my male swordtail displays no symptoms whatsoever. He does not seem to have this bubble...thing. I'm really worried because she hasn't done this before and I have no idea what this thing is.
