Came home today to find a crispy blue dot jawfish laying on the floor behind my tank. I have a screen top on my tank made with 1/2" netting. I'm about to go to H.D. to buy 1/4" netting. My question is, will this be small enough, or should I go smaller? If i were to go smaller would it inhibit the light noticeabley? I feel bad, and dont want to come home to anymore carpet surfers if I can do something about it.
