I have two bullfrog tadpoles in my classroom. They are living in a 10 gal. aquarium. I use spring water and pump for filtration and circulation. I have had them for about 4 weeks. Back legs just showed up last week. Saturday I was in my classroom and they seemed fine. Came in this morning and one had died. What happened? Do I need to lower the water level because the back legs have started to grow? The lady I got them from sells them for ponds. Most people just put them in their back yard ponds and forget about them. She really did not know what I should do to help them thrive in the classroom. Any ideas would be helpful. Thanks!
