With the current rage of Rimless aquariums comes a new line of aquariums from Mr Aqua. These new rimless aquariums feature the rimless design and feature a extra fine silicone finish. These aquariums are available in a variety of sizes and designs. Marine Depot has recently started to carry these in the traditional rectangle size in 11 gallons and up. Prices starting at $51. Which is a bit steep for a 11 gallon tank, considering you can hop on over to Walmart and spend about $10 for a mass produced 10 gallon tank…although that will get you the dull looking black frame. And who wants that? A 11 gallon rimless aquarium will make a beautiful nano aquarium.
