How do you know if Chaeto is receiving enough light?
I have it placed in a soap dish on the back wall of my tank high up to the surface, so the bulbs are a few inches in front of it, not directly above the chaeto
Its only been in a few days and seems fine so far, but how will i know if its not happy?
