ok so our monitor is rubbing its nose on one pain of glass in its aquarium its a 100 gallon octogon style, its really big and the monitor is only 1 and half ft long.it has LOTS of room, and i do know about all the requirements of keeping them, he should hopefully reach 6-7 ft. anyways, he rubs it only on one pain out of 8 and he is slowly getting a mark on him. if i rotate the aquarium he will still do it to the same pain of glass. i dont understand, any1??
