Congrats on the Tokay. I love them. He looks fine for now. With mine I definitely noticed that they do better in larger cages. Have a pair in a 20gal and then a pair in 30gal. The pair in the 30 are growing faster, out in the open more, laying more eggs. So I will be moving the pair in the 20 into a larger tank soon.
Gotta love their attitude huh?! LOL my sister almost fell out of her chair laughing when I was doing a quick clean up in the 30 over the weekend.. I don't know how many times I was begging my boy not to bite me while trying to reach past him.
Here is one of my hatchlings:
