I have 2 corns about 5 mos old. I feed ftp's every Thursday. On occasion, I'll give them 2 each if they are small. This past Thursday one of them ate both of them at the blink of an eye and my snow only ate one and was not interested in the second one. So, I offered it to my other one and he ate that one too. He hasn't regurgitated or anything, seems great! So, is it possible to feed them too much or is this a sign I need to go up to the next size?
