Thank you all for your replies.

I've had to return the Cichilid food I bought, he tried to eat it but it all kept popping back out of his mouth until he just gave up. I then bought some ReptoMin instead earlier today (glad to see it was recommended here after the fact) but he doesn't seem to recognize it as food yet, I had to scoop them all out of the tank(it doesn't help that he doesn't know I'm the 'food bringer' yet and swims away when I open the lid). I'm going to try and get him to go after them with some of the bloodworms in the water, he knows that's food already but it spreads around too thin for him to get it all.

I'm really hoping I can get him up to a healthy size and weight and I'm really glad I found a place to help me do that. I'm keeping my fingers crossed that he'll be with me for at least another ten years even though I had *no* idea they lived even that long when I offered to take him.

I just hope the goldfish don't mind their smaller accommodations. But it's better than being chewed on by a frog I guess..

Thanks again!
