Hi guys, i was wondering if anyone would be able to help me out.
A friend i work with asked me if i could look after her fish while she is on holidays for 3 months. I thought it was just going to be a gold fish but it isn't. She said she got it from a friend, who got it from a lake or river, but she doesn't actually know what kind of fish it is. The tank is cold and fresh water and without aeration. The worst part is she didn't give me any food for it, but she said she just feeds it pellets you can get from the super market.
I was wondering does anyone know what kind of fish it is, and what im actually meant to be feeding it because it doesnt look like it could survive on just pellets. Also if i should have some sort of aeration system in there.
Also i live in Queensland, Australia, if that helps to identify it. Thank You!!
