Aquarium Moss Comparison Guide

There are numerous species of aquarium moss that are popular in the hobby and it can be overwhelming (in a good way) to decide on the perfect moss since there are so many choices. So we've come up with a simple comparison guide to help you decide. We'll be covering the following 5 different aquatic mosses: Java Moss, Christmas Moss, Mini Christmas Moss, Spikey Moss, and Peacock Moss. Below is a reference photo of each moss in that respective order.

Java Moss

Java Moss is perhaps the most common and hardy of the bunch. It can survive nearly any tank environment and water condition that it's thrown in. It doesn't demand much and has a stringy growth pattern. This is a great filler moss that will help add darker green accents to your tank in tight spaces where plants such as Anubias or Ferns cannot be attached or where stem plants cannot root. This moss is our choice for any low tech/low light setup we create. If left untrimmed, Java Moss will grow to look unruly and wild.

Extremely hardy
Low maintenance
Budget-friendly

Christmas Moss

Christmas Moss is a great alternative to Java Moss due to it's unique shape. As the name references, this moss is named after common holiday conifer trees due to its thicker and triangular shape. This moss tends to grow flat which makes it an excellent choice for a foreground accent that can be left untrimmed for a long time. Christmas Moss tends to grow slower than Java Moss and will take sometime to adjust to a new aquarium setting. However, once adjusted, this moss will provide a nice full appearance that is pleasing to the eye. This moss benefits from CO2 injection and will result in a substantially increased growth rate.

Mini Christmas Moss

Mini Christmas Moss provides all the benefits of regular Christmas Moss but in miniature form. Due to it's smaller shape and size, it provides an even thicker and fuller appearance when compared to its common counterpart. The biggest difference at first glance however, is its color. Unlike the mosses mentioned on this page, Mini Christmas Moss is brighter and more lime green in color. This is a perfect aquarium moss option for those looking for a brighter moss or a more uncommon moss in general.

Highlights

Very thick appearance
Bright color
Uncommon and rare

Spiky Moss

Spiky Moss is best described as a larger version of the more common Christmas Moss. If grown in optimal planted aquarium conditions, it will grow very thick and has the ability to provide more coverage than Christmass Moss, quickly. If grown vertically, it will naturally provide a tall Pine tree-like appearance.

Thick appearance
Provides great coverage
Uncommon and rare

Peacock Moss

Peacock Moss was given it's common name because of its growth pattern. When grown in optimal condition, this moss will send out new shoot-like branches that ultimately form into a shape similar to that of a Peacock's tail feathers. Peacock Moss is a softer moss when compared to Java Moss. This is a great moss choice for softening aquarium hardscape such as Manzanita Wood.

Highlights

Feathery and soft appearance
Uncommon and rare

Choosing the best moss for your tank is ultimately dependent upon your own preferences. Our most common uses for aquatic moss include attaching to driftwood to hide unnatural-looking cuts, softening jagged and harsher rockscapes, accenting, filling in hardscape gaps, and much more. There is no right or wrong way to propagate moss in a planted aquarium. We do suggest splitting into equal portions and tying with cotton thread or attaching with super glue. However, whatever your style, the amount of ways to use moss is endless.
