Currently i have 6 RETF in a non-living tank (fake plants). The tank is a nice size, Exo-Terra 24x18x36. I feed the RETFs by releasing crickets in the tank and letting them hunt on their own. It's been working out great for over a year now. Problem is I have to hunt around for dead crickets every couple of days or it starts to smell real bad in there. The crickets have their own water and food dish by the way.

I am planning on building a new living vivarium for them. Real plants, real moss, water fall etc. I was pondering the idea of putting a shallow glass tray (2"deep) on the ground as a feeder (glass because crickets can't climb and get loose). This will hopefully allow me to clean out dead crickets easier and get a rough idea on how much the frogs eat daily.

My question is, would this work? Would my frogs, who have been used to hunting around the tank for their meals for over a year now, adapt and get the crickets from their feeding tray? Or, should I just stick to what I have been doing and releasing the crickets to wander the tank?
