Starter kits include everything needed to hatch and care for the brine shrimp: a small plastic aquarium, a water purifier, instant live eggs, growth food, and an illustrated instruction guide.

Descriptions and reviews report that the toys can swim in up to five directions and have been noted to dive as deep as 6 feet; reviewers commonly praise their realistic swimming motion and directional movement.

Many smaller robotic fish use two LR44 alkaline button cells, while at least one larger model requires three AAA alkaline batteries (batteries not included).

Review summaries highlight strong entertainment and engagement for children and commonly praise the toys' realistic swimming motion and directional movement.

The results include brine-shrimp starter kits (with instant live eggs and starter supplies) and water-activated robotic swimming toys that come to life when dropped in water.

Product details state these brine shrimp can live up to two years with minimal maintenance.

They use water-activated technology that triggers swimming motion when submerged; some models also include a water-activated color-change feature.
