It's almost 2 months since I got the BD from Petco and trying to get everything right to make sure he is happy and healthy. Had some issues at the beginning but got it fixed by changing substrate, lighting, etc. Now I'm concern with his BM. At the beginning he had BM once a week, black and white- chalky and on the harder side then he stpped BM for about 2weeks, got that taken care of and now this week, he BM twice yesterday and today and it's on the softer, watery side and it's brown. He also seems to be eating a lot more veggie than several weeks ago and he's been walking back and forth the tank, having his mouth open sometimes in the last two days. He does not seem to be stressed because he's eating and sleeping well so just wanted to understand the signs of stress in case I'm not looking for it correctly.
