"VWR"

Place these eggs in a brine solution for two days in order to make the shrimp (Artemia) hatch. Our special processing technique allows you to store the eggs for nearly indefinite periods of time. 7 grams.

Create a suitable home for fish, brine shrimp and other marine invertebrates. A 450 g bag will make three gallons of sea water (1.020-1.025 specific gravity). (Please note: This item is recommended for use with saltwater aquaria only.)

The culture supplied includes copepods in various stages of development.

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".

Easily compare the different types of structures in a variety of small freshwater crustaceans with this convenient freshwater culture mix.

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

Crayfish are a mixture of Orconectes immunis and Orconectes virilis.

Carassius auratus

Poecilia reticulata.

Brachydanio rerio.

This brightly colored marine anemone has unusually long tentacles, making it stand out in almost any aquarium.

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.

The nocturnal hermit crab uses “borrowed” shells to protect its relatively soft body, changing shells as it grows larger.

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

Black Planaria are a flatworm commonly used in science fair projects. They do not bite and move very slowly, making them easy for young students to observe.

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.
