I remember a while back we debated about the best food source that could be grown at home. I'm not going to go through the rigors of raising shrimp, but I did think that freshwater mollies might work out. I have a 55 gallon freshwater tank that I could use as a breeder for mollies. From what I hear, they spawn quite often and the live fry grow at a fairly good pace. If I were to get 2 or 3 males with 3 females for each of them I figure I can have a ton of fry around in a short time. Then, I can use these guys to feed the 2 octos that I have. Has anyone tried this? The only questions I have are how long it takes the fry to mature and how often the mollies will breed. Let me know what you think.
