Question: Red area on albino axolotl?

[bluebosnian]

Hi everyone, I just started taking care of a juvenile albino axolotl a few days ago. It seems to have a dark red color on his side but I cannot tell if its blood or maybe his body parts on the inside? Its been eating fine and not rejecting food. All tests come back fine (PH, water hardness, nitrates/nitrites, temperature is good). I also apologize for the bad photo quality. I increased the brightness on the first photo to enhance the area I'm talking about.

It'll be one of its organs and it's fine ☺ I'm going to guess liver and someone far cleverer will no doubt advise.

Thank you so much! I was really worried I appreciate it
