I've written about these guys before, but am still in the dark. Can you-all help me identify the type of roaches I have? They are oval, about one inch long and 3/4 inch wide. Their backs are slightly domed. They are brownish black, fading to mahogany around the edges. They can't climb the glass. They are of two types. One has a wing-cover-like carapace, and others remind me of armadillos. Are they different species, or perhaps different sexes?
They readily climb my fingers with their clingy little feet. That part worries me. Are they avoiding or searching-out something? They are in a glass tank, number about twenty, and two died, to my chagrin. Finally I see a bunch of tiny ones, so at least they can reproduce. The tank is on a human heating pad set on low, and the floor reads 85F on a non-contact thermometer. I feed them crushed Zoo-Preem Fruiteblende bird kibble, and greens. I keep mayonnaise-caps full of gravel and water under there, and lay a piece of cardboard (with the edges bent down so it's like a roof to them) over almost the whole bottom, which I think they like to hide under.
Any advice on identity and better care? If so, thank you for your time.
Roger
