This is comming from someone with no expirience in ray keeping, but if the ray is wider than the tank, im guessing it might try and escape, i dont know if theyr that intelligent.
Normaly they wouldnt be able to chew trough, but maybe if they where trying to escape?
Anyways, your probaly just gonna end up with a pair of heavily stunted rays )
I hope someone is gonna confirm or correct me, as said, i just started my making my own "ray plan" with tank sizes, ray species and all that stuff![]()
Good luck!
