Hello everyone, new here and its a pleasure to meet you all. I'm a new dad to a 3 month old Mexican Red Knee female. So far everything has been going well, we got her in a 20 gallon tank with top soil and a a few plants, and a pad heater. But in the past few days she's been doing something unusual... as you will see in the pic, she has locked herself in lol! My question is, what is she doing? I know they are burrowers etc.. but why lock herself in? Is this her way of saying GTFO or.... Any insight is appreciated, this way we get to know her behavior. Thanks!
