LOl I assumed all the tanks had opae in it. Congrats on the 40 years. Your Chaetomorpha Algae is nice and dark green. Mine is half dark and have light green. Any idea how to keep it dark green? As far as lighting it's in a 6 gallon tank with 18w flourescent.
The bulbs I'm using are 6500k

Daylight spotlight, seem very intense 370 lumen don't know how many lumen your 18w flourescent give off ?
the Chaetomorpha was paler when it arrived but soon greened up under the light the first tank cycle water it was in was 20ppm Nitrate. I give it a stir turn over every day, I've no Opae ula yet still cycling the tank just 1 Bamboo Shrimp in the small tank
