    Gravel is not a requirement for any type of tank you keep. However, it provides your shrimp with an added level of safety since it provides them something to hold onto while they peruse the bottom of the tank for food. Less stress = happier shrimp.

    With gravel, it would be easier to maintain PH level if you use the right soil. Without it, you will be constantly aiming for good water change

    The main disadvantage of a tank without gravel is that you can't rely on the massive amount of nitrifying bacteria contained in the substrate. In most cases, you'll need to do a lot more water changes.

    Also, unless you're using ro water, you most likely need the substrate to lower your pH and kH.

    It seems like almost every breeder uses bare bottomed tanks except for shrimp breeders. That's why I never considered setting one up that's meant to house shrimp through sexual maturity. I have however been moving some juveniles to a bare bottomed tank with a well cycled sponge filter so I can do larger feeding and then just vacuum out the excess food. They'll be moved back to the main tanks once they grow up though. We'll see how it goes.

    better option is to have a 1 inch layer of active substrate, it will help keep your water the same parameters constantly. That is important for breeding shrimp. Also the baby shrimp can eat the bacteria and microorganisms that live on the gravel, so good for breeding too

    Hey Jakub, I know some Germans now do alike, relying here on the reports from Kurt Mack, who runs every breeding tank bar - without gravel.The idea behind is to have every leftover quickly removed. Mack even attaches the food (stinging nettle) on a string ti have control over it's parts.

    wow, what would the advantage be to the bare bottom tank?

    I know in breeding fish it's easy for keeping clean and catching fish, but with shrimp, what would be the purpose?
