This pack of quintuplets are all about 1'' in diameter and provide plenty of foliage to add some neat decor to your tank. If you're raising fish, shrimp, or bottom feeders, marimos offer plenty of food for your fishies to eat- being that they're basically sponges of algae.

They're perfect for Betta tanks or bunched together for larger aquariums- like a standard 10G!

The more, the merrier, right?

Actual size may and will vary. They'll likely have shrunk when you receive them, but plop them in the water and they'll restore in size. This process takes a few days. They'll also turn into a dark green and healthy color once they adapt to your water conditions.

These gorgeous moss balls will be the main attraction of your betta, shrimp, or fish tank. (Sorry fish.)

Place them next to each other, stacked, or spread 'em out!

Each Marimo will measure about 0.5", which is just enough to add some green to the tank without taking too much away.

Actual size WILL vary. When you receive it, it'll likely have shrunk due to dehydration. They also may be flattened. Simply mold it back into a sphere and plop it into some tank water. After you submerge it in your tank, it should restore in size and get that lush green look we all crave!

This item is available for US residents only. Shipping is free and will take about 3-6 days.

You'll get a pack of QUADRUPLETS (4 marimos). Each ball measures slightly under 2" in size (will vary between 1.4"-2.0") and offer enough green to fill a medium aquarium. If you really want to show off your moss balls, you'll definitely want to take a gander at these!

These are sourced from the lakes of Japan. Each ball is at least 8 years old. If you're looking to cut them up to mold them into smaller balls, you may want to check out our smaller sizes. These are much too precious to cut up!

Please note that size may and will vary. They'll likely have shrunk when you receive them (and may be flattened). Just plop them in the water after you shape them back into form and they'll restore in size. This process takes a few days. This will also restore their lush green coloration that we all just find so mesmerizing! Definitely the draw of the aquarium (your fish will be jealous).

With large Marimos, you can easily add some live plants to any aquarium. These are well-suited for 5-gallon tanks and up. They'll still work in a Betta tank, but they'll displace water and take up a lot of space.

But some hobbyists prefer more plants in the tank, so it's personal preference.

These will happily float up and down depending on water conditions, temperature, and feeding time. These large Marimos each will have their own personality and coloration. Marimos of this size will naturally absorb harmful debris, phosphates, and ammonia. They'll also control algae levels in your tank as well.

They measure about 1.4-2.0''. Actual size will vary. They may appear smaller when you receive them, but once you get them hydrated again in your tank they'll restore to normal size.

This item ships free and is only available to US residents as of now. If you're located outside of the US, we have Marimos that ship worldwide.

Shipping time is approximately 1 week.
