I bought ten red bellies online about a month ago. They have already grown from 1 inch to about 2 inches in less than a month. It blows my mind that they grow so quickly. Anyways my questions are: When will they develop their red bellies? And when do their teeth become noticeable? I fed them a VERY small minnow today and one of them gulped it down by himself so i decided to throw in a bigger one to see what would happen. It was about a 4 inch creek chub and to my surprise they ripped it to shreds..... although i cannot see any teeth what so ever.
