Review on Two Little Fishies BettaMag Magnetic by Nadia Torres

Nano and Pico tanks only - and the rest of this review focuses on that context. Not a bad little cleaner. Perfectly removes small cloudy algae from glass. If you try to get rid of a form or Coraline, fuggeda will wake up. This little asshole wouldn't even think of removing coral from the jar in any way. Use the Pinball Nano (does the job of a Yeoman but is a bit fiddly) or the Mini ADA Scraper (perfect tool for the job, just sit down when you see the price). Don't worry about other scrapers for your nano or pico tank. I've bought them, tried them, and trying to use them in a nano or pico aquarium is nothing more than a elephant in a china shop. Even needle hedgehogs do less damage than other, larger scrapers.
