The amount you need depends on the size of your tank. From our experience we recommend a minimum of 1 Berghia per 50 liters of water, with a minimum of 3.
The more you have the quicker they will eat and more likely they are to find each other in your tank to mate.
We only sell the top quality Berghia that come through, and only when they reach a large size. We do not sell undeveloped Berghia and never will. These are extremely healthy and strong specimens.
