That’s kick-ass sea bass. Is that a plastic floor? If so setting a simple drainage system would be easy. Just need cut hole out with a holes saw, glue in some window screen to keeper feeders in, glue a small funnel right under it and have it drain into tupper ware like container. Really nice, just needs to be filled in more. I would also utilize those top braces more by affixing some fake plastic vines to them … it will be a quick way to add some front cover.
