The Two Little Fishies NanoMag is perfect for smaller tanks that have rock work or coral close to the glass. The inner portion of the magnet cleaner is less than 0.175″ thick allowing it to glide virtually anywhere on the glass easily. The outer portion is a bit larger letting you acquire a firm hold, quickly directing it where you want it to go. A super powerful magnet is embedded in the outer portion allowing the NanoMag to couple through glass up to 1/2″ thick.
