I have a 55g long tank and I cut the glass canopy in half so half the lid is covering the front and then there is the Satellite Led + and then the little extra plastic piece in the back. So if they are leapers they'd have to go up and through a small gap about an inch or two on each side of the light to get out. Is the closed off enough to prevent escape? I can show pictures tomorrow.
