No chemicals, no risk, no collateral damage.\u003c\/p\u003e\n\u003cp\u003eAiptasia is one of the most frustrating and persistent problems in the reef hobby. Left unchecked, a handful of polyps can multiply into hundreds, stinging and overwhelming corals and consuming valuable real estate in your system. Berghia work quietly and methodically — hunting Aiptasia at night, consuming them completely, and even taking out the foot to prevent regrowth. Given enough time and the right numbers, they will clear an entire system.\u003c\/p\u003e\n\u003cp\u003eWe offer Berghia in two sizes to match your situation. \u003cstrong\u003eMedium nudibranchs\u003c\/strong\u003e are ideal for systems with smaller or more scattered Aiptasia, or for building up a reproducing population over time. \u003cstrong\u003eXL nudibranchs\u003c\/strong\u003e are the heavy hitters — larger, more experienced hunters best suited for established infestations and faster results. For best outcomes, we always recommend introducing multiple individuals, as Berghia are more effective — and will reproduce — when kept in groups.\u003cbr\u003e\u003cbr\u003eShould you decide to grow your own berghia, you can also purchase additional Aiptasia \u003ca href=\"https:\/\/www.macroalgaefarms.com\/products\/aiptasia-berghia-food\"\u003eHere\u003c\/a\u003e.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3 style=\"color: #1a5a61;\"\u003eAvailable Options\u003c\/h3\u003e\n\u003cdiv style=\"background: linear-gradient(180deg,#f6fbf8 0%, #edf7f2 100%);
