ermm well my little goldfish that i brought about 2 days ago i put in with my other one and now the new one swims at the top sideways it has a black lump on the side of it and it looks like its got a broken neck what do i do ?

me thinks its pregnant :|

I don't know what's wrong with your fish but it is definitively NOT pregnant. You should try posting in the diseases section. Other board members will be able to help you there.

When you post there make sure to fill in that box of information. It's very necessary to diagnose what's wrong.

the fish died the day after i made this post it was just floating at the bottom

I'm really sorry to hear that! I recently lost my fish too, and I know how difficult it can be. If you can fill out some of the information in the diagnosis box, we might be able to tell how it died so you might be able avoid it next time.
