Had this tank for about 2 months now, and I noticed that 2 of my cherries are pregnant. Can someone tell me how long it takes for them to give birth and if they give birth to live youngs? I notice them having eggs roughly 3 weeks or so.
In my tank there are 3 autos and 9 neon tetras. Should I be worry about the tetras eating the babies?
Oh yeah one more thing, why is one brown and the other yellow? (egg sac)
IME, people are extremely over-paranoid about small fish eating baby shrimp. Will the fish consider them meal-worthy? Probably. Does that mean they'll eat them all? Absolutely not. I had 10 RCS in a tank with 10 neons and two black neons and within a month and a half the population had quintupled. Just because the fish are capable and probably willing to eat the shrimp doesn't mean they will. Baby shrimp can be really quick when they want to be and are good hiders. If anything, unless you plan on breeding the shrimp to sell, I'd consider having a few tetras in there a good thing as it may help keep your population manageable for a little while.
I make you this promise: there is no way, as long as you have adequate foliage for the babies to hide in and you keep your tetras well fed, that the neons will have a major impact on your shimp's ability to breed and survive. They may get a few, but your population will continue to grow.
I agree with solstice here. I have 4 green neons in my nano and the shrimp are breeding like mad. I have never seen one of the neons eat an infant shrimp. I have seen a shrimp almost jump on a neon from the rock above. Just kinda scared the neon. My babies are all over the HC foliage with no problems. Heck, I'm to the point where I wish the neons would limit the population a little because that nano is going to be full of RCS!
