So, I have these feeders that take HUGE feed cups. (wasting alot of food, & if I just cover the bottom, it dries out too fast)
I have 1 Gecko in each tank, so these are way too big for them, but I love the Ledge and Larger Rock Feeders, so here is what I did...
Pre-mixed Grout + 1.5oz or 2oz feeder cup + .5oz feeder cup
Fill the larger cup with Grout
Push the .5oz cup inside the Grout/2oz cup
Wet your finger and smooth it out, add more Grout if needed
Let it dry for 24 hours, add a second cup for feeding
