The orange like fish is like platy. I guess.
How many watts do you use. Does your bulb is pinkish in color? I wish i can grow HC in low light.
Right- the orange dudes are platys. Good guess!
I'm using 24 watts right now, 6500K. My bulb is a T5 HO "FloraSun" by ZooMed. Yeah, it's a little pinkish. Sometimes I like it because the colors of the green plants and red fish/shrimp seem to be intensified by it. But then again it doesn't really look like natural sunlight. My light has room for another bulb, and I would love to put an "UltraSun" in along with what I have now.
I'll post a little video clip of my tank tonight...
