"Freeze-Dried Specimens"

Planorbids, mixed genera. Compare these attractive, spiral-shelled, herbivorous freshwater specimens with other snails. They will eat aquarium plants

Philodina sp. Easy to culture and easy to examine under a microscope because of the lack of a lorica (shell), these typical rotifers are perfect for general study. Culture instructions are included.

Create a balanced ecosystem in your aquarium with the addition of these small, freshwater algae eaters. They reproduce rapidly, laying their eggs on the glass sides of the aquarium.

These small marine crustaceans are supplied as adults, and measure approximately ¹/₄" in size at the time of shipment.

These slugs maintain a marine aquarium’s ecological balance by feeding on algal growth.

Highly aggressive. Beautiful but socially challenged, male “Siamese fighting fish” will duel with each other — or even with their own reflection in a mirror — and flare their colorful fins in an impressive display of territoriality. When females are present, males will try to “impress” them. Females can coexist; males must be kept separate. Care instructions are included. Size: 1 1/2–2".

Poecilia reticulata.

Limulus polyphemus. A true "living fossil", this representative of the class Meristomata is one of only five living still in existence. The crab is the most widely studied Meristomata because of their large compound eyes and their copper-based blue blood. It thrives in a marine aquarium such as WARD’S Marine Touch Tank. Culture instructions are included. Size: 1–3". Note: Shipped overnight. Additional shipping fee applies.

Mixed genera. Also known as scuds, amphipods are freshwater crustaceans.

Uca sp. The fiddler crab gets its name from the male’s larger claw, which it waves up and down in a fiddling motion when threatened or when attracting a mate.
