| Fluorescent Pink Coraline Algae?
I've noticed over the last couple of nights there's been some "glowing pink" stuff on my rocks in small quantity and in one are on this rock. It fluoreces like it's under a blacklight (i have blue LED moonlights).
Can coraline algae come in a fluorescent form? I've never heard that, but it would be cool if it started to spread throughout my tank.
Any thoughts? |
