Hello! I'm new to this site, but I looked around a bit and thought I may find the answer to a problem I have had. I am a pround owner of african dwarf frogs and have been for quite some time. However, I went out the other day and bought 2 more lil fellas. I placed them in our tank along with the others and all was well. After I watched them a while, I left for about 2 hours and came back and realized one of my new ADF's wasn't moving. I then realized the little guy was dead. So I started carefully watching the other new guy to make sure he was alright. But after waking this morning, we realized that he was on his back, and has been for a few hours now. He was still moving, but not very much and you knew he wasn't doing so great. I started to worry so I placed him in his own tank to see if he would be better. When I came home a few hours later he was dead laying on the bottom on his back. Does anyone Know why they may have died? Could it have been a bad batch of frogs?
