Whats wrong with my pufferfish?

Question

well, it had a clamped fin now it has yellow bumps on it's belly. What does this mean? (the other one did the same thing but it died) Also, I got them from Wal-Mart

Answer 1

I am going to assume you have a fresh water puffer since walmart sells no salt water.

What are the readings in your tank?  Ammonia and nitrites?  Did you add salt to the tank? If so you need a water change with no salt.

This yellow bumps how large are they?  While cysts, are a very real possiability, so are flukes, worms etc.

You need to look at the bumps to determine exactly what they look like.

Create a thread in www.aquariacentral.com and tell them what size tank you have him in, what kind of puffer he is, your water readings, and a description (or better yet, a photo) of his problem.
