DP has an old goldfish and we recently bought a new much much smaller one to go in with it.
The new one is literally a quarter of the size or even smaller. The old one has a dodgy swim bladder but I had been feeding it frozen peas and since DP cleaned the tank it had looked much perkier and spending less time upside down hence buying the new one.
I have just checked the tank before going to bed and caught the small fish literally trying to eat the big one who had got jammed against a plant at the bottom of the tank. The poor old one has blood spots around the bottom of his belly and the new one keeps going for him. I had seen it doing some fin nipping but this is quite bad and I don't know what to do. In all honesty the old one is probably on its way out and has been for a while but I can't just leave him to get cannibalised by the new one. I will try and get a small basket to keep them separate tomorrow but what else can I do? We don't have another tank. Help!
