Frequently asked questions
Why is my Willow Moss melting in my tropical tank?
It is almost certainly too warm. Fontinalis is a temperate, coldwater moss that prefers water in the 50s to low 70s Fahrenheit and tends to decline and brown in heated tropical tanks. If your tank runs warm, a Java or Christmas moss is a far better match.
How do I attach Willow Moss to wood or rock?
Tie a thin layer down with thread or fishing line, or use a little gel superglue, the same as other mosses. It anchors with rhizoids over a few weeks. Give it gentle current — it grows fuller and greener in flowing, oxygen-rich water than in still corners.
