he may spend that much time in the water bowl but that does NOT mean that its healthy. in the wild they Never sit in water 90% of their lives. they dont even sit in it when its available after breeding season. I dont think your a bad owner for allowing it but alot of people lose their frogs to water problems all the time. bacteria is usually the unseen killer. if you have a water bowl then the best thing is to have 2 water bowls and every day bleach one and use the other and the next day bleach that one and used the sterilzed one. you must do that almost everyday! frog enclosures have the Perfect enviroment for bacteria to multiply very quickly. its a lot different than a dog water dish. If you have a water feature in the enclosure then you MUST install an Ultraviolet sterlizer!!! CARBON DOES NOT KILL BACTERIA. after so many unusual frog deaths in water its time to understand why. but you all can do whatever you want to do. i choose to Not use a water bowl or water feature. cage stays cleaner and i can controll the bacteria way easier too. just a thought.
