This is my second day as the owner of a pac man frog, and I was hoping my first post would be a general introduction, but I'm afraid he's having a problem already. I put a few calcium dusted crickets in his tank this evening, and he tried to go after one, but he missed and got a tongue full of coconut fiber instead. He seemed to be trying to spit some out/brush it off, and I figured he'd go on as usual once that was taken care of. Shortly after, he went into his water dish, which did at least clean his tongue off nicely. Again, figured it would go back to normal soon. Several hours later, though, the tongue is still out and I'm getting worried. He has not shown any interest in eating since the tongue incident, and he is still in his water bowl.
Here is some setup info, if it makes a difference. He is in a larger sized critter keeper with a shallow water dish on one end and a hermit crab heating pad on the opposite end. Moist coconut fiber is what I have in there for the burrowing substrate. In the middle, I have gauges to check the temperature and humidity. Humidity is currently around 80, temp 75 which I think is a little low on the temp? I don't know how old he is, but I am guesstimating his size at maybe 2 1/2 inches. Btw, I keep saying "he" but he could be a she for all I know. He has not eaten since I have had him (this is his second day with me), but the lady at the pet store said he ate two crickets on the day I brought him home. He has not pooped that I am aware of. I have looked, but am not 100% positive that I would recognize frog poop. Thank you in advance for any advise you can give me!
