I'm at my wits end. I have not been able to change the water or feed them for a week now. One got out last week, and ever since then, the other two have turned into butt-heads. I swear, I open the screen slightly and BAM, they are flying at the opening with dead-on accuracy. I haven't changed the water in a few days b/c they will be gone if I open enough to get my hand in there. I have been pouring water in the bowl from the screen so they have a water source. It's just a nightmare. Does anyone have any suggestions? I just have a 20 tall tank, with a screen and a hood with a light that I keep on partially. The temps and humidity are consistant and well within range. They have lots of hiding place with three plants. They should feel secure since I have 2 sides covered with a leaf background. I've had them for awhile and don't seem stressed or like they want out unless that lid opens! Grrrr! They are really frustrating me. I'm scared one will get out and I won't be able to catch them and they will die. Please, any suggestions will be welcome.
