One of my guppies has a bubble (about .25" in diameter) growing from it's underside. What is happening??

Question

It swims around fine, and has a regular appetite. Is it pregnant? Is it losing scales? Is this a contagious condition???

Answer 1

Could be a tumor or a paracite. Try to upload a picture so that we can give you a better idea.

Your fish might be ill.

Try to upload a photo, it will help.

Answer 3

possibly a parasite or some sort of a tumor or growth. as for losing scales it really depends on the condition. veterinarians are trained to handle fish and probably would be the best person to ask.

Answer 4

this is the nest the fry and eggs will be laid in so yes she is pregnant.
