Mystery Snail
Pomacea bridgesii
Mystery snails are popular aquarium snails known for their vibrant colors (gold, ivory, blue, purple, black), algae-eating ability, and entertaining personality. Unlike pest snails, they won't overrun your tank as they lay visible egg clutches above the waterline that are easy to control. They're peaceful, hardy, and safe for planted tanks.
