My toads are in a fully aquatic environment. I have a 40 gallon long aquarium for 5 toads. The aquarium has about 3 or 4 inches of water. They have rocks and logs to sit on when they need to come out of the water. They spend 75% of their time in the water. I feed them dubia roaches and feed them on the rocks. There are two large flat rocks that stick about an inch out of the water. I just dump the roaches on the rocks and they don't go anywhere. It works well.
