How escape proof does my tank need to be for CPO's?
I am currently setting up a tank for a pair of CPO's. I have read about the necessity of having a lid, which totaly makes sense to me, but now i am wondering if i have to adjust the opening for cables. The aquarium (Fluval flex) also has a seperate compartment for its pump and filter where they could get into if they should decide to climb the back wall. How cautious do i really need to be here? Any shared experiences are welcome!
