Blue is about 2 1/2" - 3" long. I just took a few picture to send you to see how the shell looks and the size of him but I don't know how to attach them. HELP please.

The fish I just buy 6-8 at a time and put them in the tank. He eats them when he catches them. All other feeding is done out of the tank. I use to feed him every other day but but a about 5 months ago I started feeding him about 2 times a week. Lately (last few monts) he has eatten nothing but fish. I still offer food in the seperate dish but he will not touch it. I have offered crickets, meal worms, pellets and earth worms.

The fish usually last about two weeks. The first day they are put in he will swim around almost all night catching three or four of them. Then he may eat one here and there over the next weeks when he can catch them.
