egg bound?

[Tery]

I've got what i think is some kind of Homaloptera,I've had about a year & 1/2. Its the only one that i have , it came into my lfs as a contaminant with a bunch of the "butterfly" type loaches, and i've never seen another. Anyway, it, she? seems like its getting fatter and fatter the last couple of weeks, If its femaie, could it be eggbound? And if so, what can I do to help her. I really don't want to lose this fish. The fish is about 3" and about the diameter of a sharpie. How do i tell if this is a problem?
