Snail population control via predators - choose by tank type. Assassin snails (Anentome helena): the gold standard for snail control. Eat bladder + ramshorn + small mystery snails. 5-6 in a 20g clears population in 4-8 weeks. Won't eat other livestock. Reproduce slowly + manageably. $5-10 each. Yoyo loach (Botia almorhae): active snail-eaters in 30g+ tanks. Fun + colorful. Need group of 4+. Clown loach: get HUGE (12"+ adult). Snail-eating but need 125g+ tank long-term. Dwarf chain loach (Yasuhikotakia sidthimunki): stays small (2.5"), peaceful, schools of 6+. Best loach for community tanks under 75g. Pufferfish: Spotted/figure-8 puffer (FW), pea puffer, dwarf puffer all eat snails. Caveat: nip fins of slow tankmates. Some cichlids: jewel cichlid, kribensis (during breeding), African cichlids occasionally. Saltwater: Six-line wrasse + harlequin tuskwrasse + many wrasses eat smaller pyramidellids + vermetids. For shrimp tanks: NEVER add fish that eat shrimp baby. Use assassin snails only or manual removal with bait (cucumber slice attracts pest snails overnight, scoop out).
