・How to Take Care of Marimo

1. Avoid Direct Sunlight

While you might think plants need lots of sun, Marimo are an exception.
In a small container, direct sunlight can heat the water and actually cook the Marimo, which can kill it.
They prefer cooler environments, so feel free to keep them in a well-lit area with indirect light—or even pop them in the fridge on hot days!


2. Keep the Water Clean

Like any living thing, Marimo enjoy fresh water.
Change the water once a week to keep it from becoming stale.
Be gentle—don’t pour water directly onto the Marimo, as strong currents can damage or deform them.
And yes, tap water is totally fine!


3. Don’t Add Fish

It might seem cute to put a goldfish with your Marimo, but beware—fish often see Marimo as a tasty snack!
Especially goldfish and other herbivorous or omnivorous species.
If you must pair Marimo with fish, consider cold-water-loving species like medaka (Japanese rice fish), which are less likely to nibble.
