Hi fellow living reefers. This is my first post, as I am brand new to the site. I have been reading your posts & threads for a few weeks now, and thank you all for such great information. My LFS, has a large Mandarin Goby/Dragonet, that I would like to bring home.\n \nMy copepods question(s) are:\n Are UV sterilizers harmful to copepods?\n Do copepods add to the biological load, or assist the load by eating detritus?\n I have a 20 gallon fuge, how long before the copepods reproduce, to catch up with\n the Mandarins appetite. I hear they will devour 30 to 100 of them a day?!?\n \nThanks for any advice you may offer!
