i'm new to this and decided to turn my already established live rock only aquarium into a octopus tank however knowing how they're escape artists i was wondering if i need to put a mesh behind my overflow teeth to prevent it from going through if my overflow teeth are 3mm wide?
also if there's anything else i should know about it's habitat requirements please let me know!
