Bowl feeding 3 whites in one tank?

[DC101]

Hello everyone!

So, i have 3 Australian Green Tree Frogs (whites) and they are 4 months old. I have been tong feeding them and its working fine but i would like to use a glass bowl.

The only problem is, is that there isnt much room to have 3 bowls, i could fit 2, but im afraid one will eat all of them and leave none for the others.

Has anyone had experience with bowl feeding more than 1 whites in one tank using a glass bowl?

I want to bowl feed because if i go away, then it is easy for the pet keeper or whoever is looking after them to feed the little guys.

Any suggestions...?

By the way, i will probably be feeding them roaches but i will find a way so they can't get out. Maybe vaseline the sides or something.

Thanks
