Although we’ve never been much of a fan of the marimo moss balls, there is a certain quaintness to these new Nano Marimo balls from Hokkaido Japan. The Nano Marimo balls are little clumps of Cladophora algae which have somehow become tamed into growing extremely slowly. Originating from Lake Hokkaido in Japan, it is said that these Nano Marimo balls grow at a rate of 5mm per year, making each nano marimo ball about one year old. It would be interesting to see what could be done with these nano marimo balls in a nano aquascape, perhaps they’d tumble around like little Cladophora tumbleweeds or maybe someone could adapt them to grow on twigs and make them look like a tree out of a Dr. Seuss book. Freshwater aquatic moss and fern specialist Aquatic Magic is currently offering the Nano Marimo balls for sale, five pieces of Nano Marimo for about $5 before shipping or you can still get a “giant” marimo ball for $5 each.
