Shrimp & Snails at a glance
Freshwater shrimp and snails are tiny, peaceful "cleanup crew" pets that graze algae and add color and life to a tank. They're cheap, fascinating, and perfect for small spaces — a fun first aquatic pet, often kept alongside calm fish.
Crayfish at a glance
Crayfish (sometimes called crawdads) are bold, colorful aquarium pets with real personality — they rearrange their tank, wave their claws, and explore constantly. They're cheap and hardy, but they'll grab tankmates, so most live solo with a secure lid (they're escape artists).
