Flame Moss Scaper Pads Small (4.5x4.5cm) are a convenient and easy way to add moss to your tank which sinks immediately. Flame moss gives the effect of a deep green campfire once established and is easy to grow. It takes time though so you need to be patient (often the hardest bit).
Simply place a few of them in your tank and they will drop to the bottom. Shrimp love to clean moss and it's such an easy plant to grow making it ideal for beginners. Avoid bright light. Gradually and over time, the moss will thicken up and establish and if you have enough of them, you can create a slow-growing carpet and this is why they have become so popular.
Trim once a month to avoid them getting too leggy.
