Mermaid's Hair Algae (on purpose?!)
After long consideration on whether or not to buy java moss and get it to grow on the lava rocks in my goldfish tank, I've decided, no. I've had it in my tank before and it quickly turned into a salad. So I want to try what most hobbyists would consider absurd and stick Mermaid's Hair (cladophora algae) in my tank.
Sounds insane, right? Hear me out. It's a bare-bottom tank with only a few plants that I can won't mind tossing if it happens to take them over. The plan is to just have it covering the lava rocks and hope the goldfish will leave it alone.
