I have a female black neon tetra which I originally thought was carrying a clutch and was the reason she's gotten so large, but its been almost two weeks in the breeder tank and nothing's happened. Some suggest she may have dropsy, but her scales are pine combing out and I don't know if htey would due to the texture of their skin. She looks ready to burst and parts of her insides seems tobe tearing at her girth. Is this just normal for a pregnant tetra or are we talking serious disease here? Really need some help.
