That's a good suggestion, easier said than done on a large tank with minimal aquascape, my tank is packed with corals I can hardly find space for a fish trap. There is only enough room for a magnet cleaner on the sides and coral sit right up to the front pane... I know I wish I had a larger tank but it's on the second floor with minimal support, there is a double garage underneath.

I used black signboard to catch fish before in my 120g when I was shutting it down and it's easy to catch fish once they're right to the corner.
