confused

So, I've had this red oscar for a few months. Since around the beginning of December. This dude was a beast of a fish. He was a juvenile. He has lived through an ich infestation, lived in a tank while it was being cycled, and has outlived two other juvenile tiger Oscars. He's never shown any...

they where told and sold as a normal ball python but I don’t have experience with normals so I don’t know their variations. To me this does not appear to be a normal what does everyone think?

Can someone tell me what my ph lvl should be for a buttikoferi I'm seeing so many different levels online some sites say 7.8 to 8.6 and others are saying 6.5 to 7.0. So obviously I'm a bit confused how could they be talking about the same fish?
