Thank you both, I'm glad it's not a sign that he's unhealthy or anything. It is his second night in the tank, and unlike last night he is sitting on the edge of his water bowl happy as a clam...So, since I am brand new to this, I am going to have a ton of questions, and I'm going to be paranoid, haha... Should I start a new thread for each one? I noticed some small brown marks around his upper lip in the front, and I'm not sure whether they're scratches or pieces of coconut that got stuck to his face when he dove to catch his first cricket. I don't even think if I took photos it would be possible to tell, they're just small brown lines. Should I do anything? They've been there since at least last night.
