We have decided not to keep fish any more. The kids are not really interested in them. It's my fault, they wanted a guinea pig and I bought them fish. The tank is big and takes up valuable space on the kitchen worktop. I wouldn't mind if people enjoyed them but they don't.
We now have only one fish left. I can't remember it's type but it is very small despite being about 5 years old, 3cm long maybe? What is the smallest size of tank I can safely keep it in? Can I put it in a small bowl instead of the big 40l tank? I will keep looking after it properly and keep it clean, I'm not trying to kill it off, but once it's gone we are not getting another one. And I dearly want the big tank gone, even more so now there is only one fish
