The large tank in the center is used for holding a weeks' supply of adult brine shrimp, which is the main diet of the darters in captivity. The smaller tank to the left is used for feeding the shrimp a dietary enhancement before they are fed to the fish. The two small tanks to the right are used for hatching brine shrimp nauplii, the main component of the darter fry's diet.
