I do not know if I am posting this in the right place but here goes anyway. My drug addict next door neighbours abandoned their house and their pet goldfish. For eight weeks it survived with no food and when we rescued it the tank was smelly and filthy. My husband scrubbed the tank and we bought new gravel, a pump, fish food and a couple of ornaments. The tank did not have a lid so my husband cut a piece of perspex to size and drilled some air holes and "Lucky", as he is now known is thriving. I would like to buy a new hexagonal shaped tank to fit in the corner of my kitchen. Can anybody suggest where I can get one. I would also like to put a light in it and would love to have a moonlight effect. Can anybody please give me their advice as I know absolutely nothing about fish or lighting or anything like that.
