Rimless -- is it safe?
I know a bunch of people decided to not spend tons of money on an already-rimless tank, and just popped off the top rim of standard black-rimmed tanks. Is it true that the glass edge that the rim usually covers would slice up my arms every time I cleaned that tank? It's an interesting idea, but I don't want to get hurt by it.
No matter how hard you try, you cannot escape this hobby. You have been warned.
