It also depends on the lighting from where you're getting your zoas from.
When I buy from a t5 or mh system they seem to take a while to open and then grow. I'm going to convert my lighting system to t5 because I hate having to acclimate every time I get a new piece. It's not fair to my other inhabitants and most lfs/hobbyist use t5 or metal halide.
