Just a bit over a year. I have recently started dripping phyto and dosing a mix of powdered foods. The PE on it has been seen more often with lights on, which I love. So hopefully it will grow a little quicker, as it will be moving to a seahorse only tank once it cycles. I want it to be the centerpiece. I have some photosynthetic gorgs as well, but to me they just are not as good looking. NPS critters always seem to have the best colors. Eye popping colors and you do not need UV or blue to bring it out.
