Im going with lynn on this... your terrarium..needs substrate like tree fern or coconut fiber... water bottoms is really only good when breeding them...use a water bowl instead.... i also agree with bill...stick with one for now...you can definatly get him a buddy but give it a couple of weeks..learn how this frog reacts...the color pattern on him worries me alot. My frogs never turn splotchy like that and i have 14 of them. if lynn says its ok it probably is...but it really does concern me. feel free to view my website on care of your red eye: RED EYE TREE FROG - RED EYE BASICS also we are always here to help you =)
