I'm a naturalist and rescued a string of boreal chorus frog (Pseudacris maculata) eggs from one of our play area water features that is bleached regularly (the kids tend to drink out of it). I opted to keep them to provide our visitors w/ the opportunity to watch them grow. The tads have been in about 6" of well/treated tap water changed 2x weekly, and treated w/ a repti-cal slurry after the water change. There was a 10 day stretch w/ 50% water changes due to a nitrite problem courtesy of a coworker "helping" me by feeding 3 pinches of fish flakes. They've been eating algae collected from our location and boiled lettuce (depending on how successful my algae hunts were). Last week the first tad morphed out and finished absorbing his tail by Wed. He was offered flightless fruit flies Wed, Thurs, Fri, Sat and Sun and refused each day. He was not offered food Mon due to a miscommunication on my end. When I arrived at work Tues, approx 2/3 of his lower jaw had disappeared (I'm assuming reabsorbed) at which point I euthanized him. What I don't know is why. Does anyone here have any ideas/thoughts? There are 7 tads left, two have front legs and should shift to land over the next two days.
