This is an Acrylic tank, and in the case of Acrylic Crazing is cracks that typically are inside the acrylic, the cracks are not on the outside surface or inside surface but actually start in the middle of the acrylic.
also Crazing in acrylic can be caused by bad stands like it was in my case but most of the time its caused by someone using cleaning chemics on acrylic, putting acrylic in direct sunlight, or when the the tank makers use flame polishing, and weaken the acrylic and then the normal stress from the water even on an even stand causes the crazing.
