Thanks for the info. I just wish I knew what “normal” was for them. When younger they would eat from the tweezers until I thought they would pop. Now I'm lucky if I see them eat one cricket or roach. (I guess the key word is see). I don't leave feeders in the tank except for pill bugs, so I guess they are munching on them when I'm not around to see. So how long should I let it go if I don't see them for days or weeks?
