Casuarina Pine Pods (Casuarina equisetifolia) Long-Lasting Botanical for Aquariums, Terrariums, and Paludariums (6-Pack or 12-Pack)

An attractive, low-tannin alternative to alder conesideal for shrimp, snails, and blackwater-style setups.

Bring structure, subtle texture, and biofilm support to your tank or terrarium with Casuarina Pine Pods, also known as Casuarina Seed Cones. These naturally dense, pinecone-like botanicals come from the Casuarina equisetifolia tree and are a durable, low-tannin addition to any freshwater or high-humidity environment.

Each pod is thoroughly cleaned and ready for use in aquariums, paludariums, or terrariumsproviding both visual appeal and long-term function.

Why We Love Them:

Visually Striking Their natural, pinecone-like texture enhances any nature-themed layout
Durable & Slow-Breaking Lasts significantly longer than alder cones in water
Low-Tannin Release Wont overly tint water or drastically lower pH
Versatile Use Excellent in aquariums, terrariums, or paludariums for structure and shelter

How They Differ from Alder Cones:

While similar in appearance, Casuarina Pine Pods are more durable and release far fewer tannins than traditional Alder Cones (Alnus incana). If you want the visual appeal and surface area for biofilm without significantly darkening your water or lowering pH, Casuarina is the better choice. Theyre perfect for long-term setups where stability and structure matter more than water conditioning.

Great for These Species:

Aquarium Fish Betta fish, rasboras, gouramis, tetras, and dwarf cichlids benefit from shelter and natural decor
Aquatic Inverts Shrimp, snails, and plecos love to graze on the biofilm that grows on these pods
Terrarium & Paludarium Dwellers Vampire crabs, isopods, dart frogs, and springtails use them for cover, moisture retention, and climbing surfaces

Preparation Instructions:

Rinse well and boil for 1530 minutes before use to help them sink and minimize any initial tannin release. Pods may take time to become fully waterlogged but will eventually sink and remain intact for months.

Size & Quantity Options:

6-Pack Perfect for nano tanks, betta habitats, or small terrariums
12-Pack Ideal for community tanks or large display enclosures

Each pod measures approximately 1.52.5 inches. As these are natural items, size and shape may vary slightly.
