Balloon Mollie

[ebonicz101]

i noticed yesterday that one of my ballon molies has a clear bubble hanging from her anal so i kept a close eye on her and then when i went to check on her today it was still there.. can anyone help me and tell me what this could be..

We need more info.

How big is the tank? What other fish are in it? Is it cycled? (If possible provide water parameters: ammonia/nitrite/nitrate/temp/pH).

Is there any salt in the water?

What does the bubble look like and how big is it? A photo would be of most use to us. Is the fish pregnant and due to give birth?

Is she acting normal or does she appear distressed. Is she lethargic or too thin? Does she eat normally?

Thanks.
