I am just wondering if light has any effect on the growth rates of guppies. The fry that were in my community tank seemed larger and more colorful than the fry that I had managed to separate out into a separate fry tank.
humm light??? you better turn it off during night time. theny need time to rest and grow.... during day time they will not rest. ( cuz as soon as they notice people are walking by, they just swim away. how can they rest this way?)
