This weighted, natural-looking rock base is designed to work with our \u003ca href=\"https:\/\/shop.pangearocks.com\/collections\/kelp-1\"\u003eartificial kelp\u003c\/a\u003e and provides a simple alternative to permanently fixing your kelp to a large rock or aquarium structure.\u003c\/p\u003e\n\u003cp\u003eThe Rock Holdfast is designed to mimic the function of a natural holdfast, the structure used by real kelp and marine algae to anchor themselves to rocks. Unlike a permanently mounted installation, the rock is simply placed inside the aquarium, allowing fish and other marine animals to push, move and interact with the kelp as part of their natural behaviour.\u003c\/p\u003e\n\u003cp\u003eThis makes the Rock Holdfast particularly suitable for active species and dynamic environments where the aquarium is intended to change and evolve through animal interaction. Your aquarium kelp can become more than decoration; it can become an active part of the underwater environment.\u003c\/p\u003e\n\u003cp\u003eThe Rock Holdfast can be used with several of our kelp varieties, including \u003ca href=\"https:\/\/shop.pangearocks.com\/products\/giant-sea-kelp\"\u003eGiant Sea Kelp\u003c\/a\u003e, \u003ca href=\"https:\/\/shop.pangearocks.com\/products\/laminaria-saccharina\"\u003eLaminaria\u003c\/a\u003e and other kelp-inspired designs. It is an ideal kelp holdfast for creating a more flexible and natural-looking kelp aquarium.\u003c\/p\u003e\n\u003cp\u003eThe weighted base provides stability while still allowing animals to move the plant when interacting with it. This creates a constantly changing display where the position of the kelp can naturally shift over time.\u003c\/p\u003e","brand":"Pangea Rocks A\/S","offers":[{"title":"Small ( 10x6 cm)","offer_id":53219661676877,"sku":"10","price":39.69,"currency_code":"EUR","in_stock":true},{"title":"Medium (16x7 cm)","offer_id":53246589632845,"sku":null,"price":69.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0677\/4675\/8956\/products\/laminaria_esculenta_rock_footing.png?v=1668760291","url":"https:\/\/shop.pangearocks.com\/products\/eualaria-fistulosa-rock-holdfast","provider":"Pangea Art Deco ApS","version":"1.0","type":"link"}
