Hi everyone! I was doing some research yesterday and found at least several 'tropical' marine fishes in this hobby that seem to undergo noticeable seasonal changes in photoperiod and temperature - Gobiodon atrangulatus, for example, I found to generally have summer temps in the low to mid 80's fahrenheit and winter temps from the high 70's to as low as the low 70's, with photoperiods being around 14 hours in summer and 10 hours in winter. With that in mind, could I control when a saltwater fish decides to spawn by simply changing the tank's temperature and photoperiod over the course of the year? I did read at least one article on reef to rainforest that stated that the New England Aquarium, when going to breed the blue reef chromis, increased the photoperiod and temperature of the tank the broodstock was in to 14 hours and 80 fahrenheit respectively and got them spawning within two weeks. Thanks
