Indents in stomach

[fvg318]

So I've just recently noticed to odd spots on Jaks belly which are also indented as well, but he still acts normal. Poops, eats, and plays the little game I've taught him. He's just about to reach 8 inches also. Any one have any idea where these indents came from. Also he doesn't live in a gravel bottom tank, it's a rubber texture mat that I chopped up for him cause I don't want losse bottoms with small losse pieces and he could swallow something bad.

Ps. He is not happy about me touching him x.x

That is really peculiar, I have never seen anything like that before. Are there any new developments with your axie? Are the spots increasing in size, and has his behavior changed in any way since you noticed them? Check your water parameters, temperature (the basics) if you haven't already.
