Hello, I'm hoping someone can help. I'm brand new here so I wasn't sure where to post this. i currently have 6 spotted marsh 3 adults and 3 new froglets. One of my adult marsh frogs has a weird twitch happening in its legs and today I thought he was having a seizure ( i googled seizures in frogs!) his whole body went stiff and he nearly drowned. It lasted maybe a whole 30 seconds. His mouth was opening all the way like he was gulping water. They have a diet of crickets and mini mealworms and the tank is currently gravel and rocks. No live plants as I've just cleaned the tank thinking that could be what it was :-( sorry rambling, just hope he's ok. thanks in advance.
