i only asked the question because the shop i got him from advised me to take him out of the tank he is in and put him in the smallest size critter keeper as he said the frog is intimidated by lots of space and if he is in a tank too big then he will get stressed and stop eating. he still isnt eating and im worried for him. (i did put him in a small kritter keeper but then i put him back in the original tank i had him in as i felt the critter keeper was too small. the tank i have him in right now is not his permanent home as it is only just over 1 ft by 10 inch but it is tall which i know he doesnt need but hes only just over a inch big. i plan on getting him a 2ft tank when he gets bigger.
