Alight I am reasonably sure my green tree frogs are not suicidal, but yesterday i found one of them (I have 2) struggling to get out of the water in my tank so i put him back on land. then this morning I found them both in the water and i think the one is dead. again i pulled them out but want to know why? I have had them over a month and have never seen anything like this. My tank is a 110g that I made a vivarium. I also had 4 anoles in it but one died i think it had a parasite, either that or it was just getting bullied out of the food i'm not sure. the one thing that i did change with the tank before my frogs became suicidal was i added some aquatic plants that came all the way to the top and floated kinda like a Lilly pad, i don't know maybe the tried to go on them... i am so new with reptiles and amphibians any help is welcome. this tank is also in a school so avoiding suicide would be good .
