Apple snails, or ampullaries (representatives of the genus Pomacea), are among the most popular and striking invertebrate inhabitants of freshwater aquariums. Due to their impressive size, active behavior, and, most importantly, their wide range of color morphs, they have quickly won the affection of both beginner and experienced aquarists. However, to ensure these mollusks have a long and healthy life, strict maintenance rules must be followed, especially concerning water parameters and diet.
