Not really sure if there is already a thread for this, but I'm new here so please excuse me lol. I have an African Clawed Frog (i think), and have had him for 21 years. I just noticed today while cleaning his tank that his inner claws on both rear feet are missing and red (see images). I am very concerned and was looking for some advice and known causes of this. I read that these wounds should heal themselves. Any suggestions??
Also, I attached a picture of his tank set up. Just recently put him in this set up and just bought the filter two days ago (hence why I cleaned the tank today). Is this filter ok for him?? It's one of the waterfall types for a 10 gallon tank, which is what his is. He seems kind of freaked out by it, but I think it's cause it's new to him. Any comments are appreciated. Thank you in advance!!
