I got mine with a large egg sack still on it. I know you should wait till it falls off and see if it eats but, I wanted to start with a fetus. YES, they ARE VERY FRAGILE at this size. Make sure water param's are pristine, temp's stable, and not to stress your fish. I feed mine crumbled up hikari food sticks to start out with and also FD brine shrimp. I would stick to the foods sticks first to try and get the little dude used to it. Later down the line start to vary the diet up and dont over feed, your baby might get bored of what its eating and stop accepting food all together. Once you hit about 6 inches or so your fish should be pretty good, and at 12 inches your pretty much golden. I actually prefered to start like this so I could watch the little dude grow and know what his diet consisted of.
