Lids on a FOWLR?

Hello

@GreenSpottedPuffer I don't think it's not popular. In fact I was just thinking ... because most people in Asia lives in high story apartments, some of the people put fishing line like fences on the balcony for safety. Well it's actually a steel cable but it looks like thick fishing line from a few feet away. Here is an example.

Anyway for the fish tanks real fishing lines can be used and it should be quite visually acceptable and not too distracting.
