I had two goldfish in a 60L tank for about 5 years. When one died, aged about 5, I replaced him after a couple of months (I couldn't face 'replacing' him any sooner) and all was grand for a while.
However, my other fish died 2 years later aged 7 or 8.
Now I have one (recently gotten very large) goldfish in a 60L tank. I don't want to get another fish because the tank is so small. But my fish is miserable. She just sits on the floor of the tank for most of the day and hardly swims around much.
She clearly needs more room, and company. Should I think about finding someone with a fish pond to take her, as I assume she'd be happier with more room to swim about and other fish.
If this is the way to go, how do I find someone with a pond that would take her? Is there a re-homing fish website or something!?
