I need some advice/insight on what to do with Sparkie. He is OLD (between 5 and 6 years) and lately things have tooken a turn for the worst. All he does is lay on the bottom of the tank with his head and neck curved upright or he is up at the surface "sitting" straight up and down.. His qaulity of life is horrible right now and Im not sure weather it's cruel of me to keep him alive when he can hardly get around. Im very attached to him after having him for over 4 years so it really doesn't seem right to put him to sleep but it also doesn't seem right to keep him alive when he's like this. Any insight helps, thanks.
