Your pond sounds awesome! I personally wouldn't risk my Asian aros, so if I were in your situation I would sacrifice the aesthetics for the safety of my fish. Maybe if you get a black swimming pool net (cover) it wouldn't be so intrusive ... ? What stock do you currently have in there?
Anyways, good luck and please post some pics of the pond, net or no net.
