With the Biube Pure you can create stunning environments for your fish by aquascaping and this is what the biUbe Pure is all about. Choose from two different styles of biUbe. The standard biUbe is supplied with black or silver lid and base bands. The biUbe PURE is available in crystal clear or blue tint options. The slender shape of the biUbe allows it to sit in places where a biOrb may not quite fit.
