i have two tigerleg monkey frogs (a little more than an inch long) that i got almost 9 months ago at a herp expo... they were supposed to have been captive bred.. but who knows.. at any rate.. they are in a 30 gallon with a shallow water area, a ton of plants, moss, and climbing vines.. they get misted twice a day and fed dusted crickets 3 times a week..

one seems to be getting bigger than the other, and he or she, is usually a nice green, except when sleeping.. the smaller one however is always a dark olive green... i cant for the life of me remember if it was like this when i got it.. i am wondering if maybe it is sick? still eating normally and climbing around the tank at night... ive tried to catch him early in the am before i go to work to see if maybe he is getting lighter at night.. but he always seems to be a dark brownish green... is this normal? this is my first time owning these guys and want to make sure they are both healthy and happy.. they were about the same size when i bought them, could the larger be a female? i am worried that the dark coloration is maybe due to stress... can someone tell me if this is normal or not? am i doing something wrong? thanks in advance for replies...
