I do intend to add a 1/8 inch mesh screen from BRS with a DIY curve for the bowfront as opposed to the glass top only because I find cleaning the glass to be very tedious. I saw plans for one on a thread here ar R2R. As far as the brace modificartions go if that is not a good idea then no worries. I wont do anything that may cause trouble down the line.
Im looking for a relatively easy experience so I do hope to understock and rely on the fuge, skimmer and decent size water changes.
My plans for adding fish down the line are an orchid dottyback, a sand sifting goby, and a small school of cardinal fish. I think that would be about as much as I would want to put in there. Maybe some snails as well just for cleaning
