Bloated Nwon rainbow

unfortunately didn't make it, must've been parasites, went to the pet shop yesterday and bought some parasite treatment. Thanks for the help, he ended up just rolling over after a while, quite unexpected actually from how he was behaving

 

Sorry to hear. The best you can do is get a quarantine tank. Just a basic set up, and quarantine all new fish. That way you keep disease and parasites out of your main tank. What meds did you get?

 

My pet shop didn't have anything very specific, so a bought a gill, fungus and parasite treatment, have put together a little quarantine tank for new fish

 

Sorry to hear @Bradley Rees ...

Glad you have decided on a little quarantine setup.. its worth it
