I was thinking of is which is the best way to feed TREF, i am new with this kind of animals but i have another long experience having iguana, aquarium and aquatic turtles, so in the case for turtles i like to giving them small fishes so that way the turtles have to swim a lot to catch the fishes and make some exercise, so for the frogs is the better way to let the crickets around so the frog can make a little exercise or well is better and a healthy way to use the cricket bowl technique, so for the bowl cricket technique i was wondering on how the exo terra feeding rock http://www.exo-terra.com/en/products/feeding_rock.php will work with the frogs
