Sapucaia King Pod | Lecythis pisonis
Product Description: The Sapucaia Pod (Lecythis pisonis) is a very special seed pod we have sourced from the Amazon Jungles of Peru in South America. Their hard and woody composition makes them ideal in both bioactive enclosures and botanical aquariums as they can last for literal years in these ecosystems. They are entirely hollow, capable of allowing plecos, dart frogs, or apistogrammas to seek refuge or even spawn in these natural ecosystem materials. Keep in mind that they will require an extra-long boil or multiple days of soaking in the aquarium in order to become waterlogged, and the tannins they produce are a wonderful soft brown color. They will grow intense biofilms at the beginning of their journey in your botanical method aquariums, so either be prepared or give them a thorough initial boil and clean out all residual fruit from inside of the seed pod. We have found that in aquariums of 10 gallons or smaller, it is best practice to clean out the residual fruit unless you have fish like plecos that will consume it quickly.
Not for Human Consumption. Preparation Required.
Quantities: Available in 1c Sapucaia Seed Pods. Measures 8-1" across and 6-8" tall. This is a natural product, and variation between leaves and botanicals is expected.
Aquarium Botanical Location: Peru.

Home is getting more natural
While the warm tones of tinted water and layered botanicals may first catch our eye, their true value is ecological. In South American habitats, fallen leaves, seed pods, and woody debris shape water chemistry, soften light, and sustain the microbial food web. Recreating these conditions allows us to mirror the rhythms of blackwater rivers and flooded forests where South American fish, amphibians, and invertebrates feel most at home.
Botanical FAQs
Compostable Packaging Promise
Our packaging is designed to return safely to the Earth, just like the botanicals inside. Every bag is BPA- and Phthalate-free, GMO-free, and contains no animal products. Each meets ASTM D6400 composting standards, ensuring it can fully break down in a home compost bin.
What are the Fluffy White Growths on my Botanicals?
That’s biofilm and fungi—what we call the “goo phase.” It’s one of the clearest signs that your aquarium is alive and functioning. These growths wax and wane naturally as botanicals decompose. They’re harmless, even beneficial, and will disappear on their own once microbial populations stabilize.
Will botanicals lower the pH of my water?
That depends entirely on your source water. In very soft or RODI water, botanicals can gradually lower pH as tannins and humic substances accumulate. In medium to hard tap water, buffering capacity often resists these shifts, and you may not notice much change. At Betta Botanicals HQ, our very hard water (350+ ppm) shows almost no pH change unless we use botanicals like Alder Cones or Macaranga Leaves.
When should I replace leaves or pods in my tank?
We recommend allowing botanicals to fully break down into detritus, since this fuels microbial life and enriches the substrate. You can remove them once they stop tinting the water, but you’ll lose some of their ecological benefits. Each time you add new botanicals, follow proper preparation and observe your livestock until you learn your aquarium’s rhythm.
Are your products just for bettas?
Nope. Our botanicals are safe for almost all aquariums, terrariums, vivariums, and paludariums. The only exceptions are goldfish and axolotls, which may ingest small pods like alder cones or casuarina cones. For those species, we recommend large leaves such as Indian Almond, Loquat, or Jackfruit.
What are Tannins?
Tannins are natural compounds released by leaves, seed pods, and bark as they decompose in water. They soften water, gently lower pH, and create the characteristic tea-stained tint found in blackwater habitats. But their role goes far beyond color—tannins fuel beneficial bacteria, fungi, and biofilms, which form the foundation of a healthy ecosystem. They also offer mild antifungal benefits and help reduce stress in fish by replicating the natural conditions they’ve evolved in. At their core, tannins are plant-derived antioxidants that connect your aquarium to the same processes at work in wild flooded forests and streams.
- This pod is even bigger than expected, and adds a really nice dimension to my tank.
- Very efficient in lowering pH. Good in providing tannins, shelter for fish and acidity.
- Good size for bettas. My fish use it for hiding and playing at times.
Just as pictured, had some difficulty getting it to sink but put a small rock in it and down it went
It was a lovely product but it was a bit big for my tank so i gave it to my friend. It did have trouble staying down so I had to weigh it down with rocks but other then that it was a great product.
This pod is even bigger than expected, and adds a really nice dimension to my tank. Even the larger fish go in and explore it. Considering ordering a couple more to fill my 75 gallon tank with funny giant pods. Being flattened on the bottom, they would also make a good pencil holder for your desk.
This pod is HUGE, like unexpectedly huge, which I suppose would make sense for the price, so I'm super happy with everything! Meant for my small 11 gallon, but definitely going to be much better for my larger 110 gallon.
Second time buying this seed pod. Very efficient in lowering pH. A lot of biofilm at first but the rest of the way was v good in providing tannins, shelter for fish and acidity.
Good size for bettas. My fish use it for hiding and playing at times. Nice addition to my aquarium botanicals.
Perfect.
