I just bought a new Beta fish two days ago, and really don't know much about fish at all. I put transferred it from the pet store water into a small tank filled with bottled water at room temperature. I used the drops to neutralize the ph as the pet store recommended and transferred the fish. After the first 12 hours, I noticed the fish had some strange "fuzz" on a little part of it's body. I though maybe it was from the fake plant in the tank.
When I came home from work today the "fuzz" has spread. It is in several places on the fishes body, fins, and around one eye and part of his face. The fuzz looks like foam, or wisps of cotton or soap suds, or maybe some type of fungus!
The fish's tale also looks like it is shredded as well. I'm going to remove the fake plant in case that is the problem. And he is not acting like "himself."
Please help! Does anyone know what is wrong with my fish and what I can do?? I feel so badly!
