Thank you! I tried one a year ago, thought they preferred higher par and put it right at 400 par. Roasted it... It was a white skeleton the next day. That's good to know yours are both happy there so I'll have to try again but maybe acclimate it to higher lighting slowly.Honestly not really too sure. They are both fairly close to each other in the tank and get around 400 PAR, and fairly decent flow. I do run my nutrient levels higher now, but they haven't seemed phased when they were lower. Color has increased though.
