I have both dendros and balanos my balanos are starting to open up with the lights on (not all the heads open and I spot feed during the day to help them open up) and they both open up beautifully at night. How can I get them to open up during day time? And I got one hell of a deal on both I paid about $50 for my balanos (about 15+ heads) and $25 for the dendros (with about 13-15 heads)! But how do I get them to open during day? Should I put them somewhere dimly lit in the tank and then bring them out toward the light over time?
