I have been doing more reading in preparation of purchasing a couple frogs and have discovered that it is best to figure out the fruit fly culture thing before purchasing. My question is... How many fruit fly cultures should I have going at once? I have seen alot of threads on how to culture them but the ppl writing them always have a dozen plus going at once. I am assuming this is because they have multiple setups and alot of frogs to feed. I am planning on having 2 frogs. How many cultures do I need to feed the frogs while ensuring the viability of producing cultures?
