My mum said i may be able to get a fish soon, but i am relatively clueless about fish or how to look after them. I would want a fish that is fairly easy to maintain and care for, and quite cheap to keep as well. Also, it would be helpful to know the size of tank, what kind of food and what decorations are needed. as i said, i have no experience with fish, so i would need everything to be explained, thanks!!
