I know everyone in this hobby has this hubris of speaking from a perspective of talking to others as if they have zero experience in this hobby. So to that end, Ive been keeping reef tanks since the mid 90's. In that time Ive lost 5 fish, two to jumping, 2 to haddoni carpet and clowns baiting the fish to chase them into the anemone, and one due to what I like to call a "gf incident." Anyways, I put a mesh top on here, and the real reason is the tank is too shallow and two fish lost is too many in my mind. I appreciate the links, Ill check it out thanks.
