Loquat Leaves | Eriobotrya japonica
Loquat Leaves on the Surface:
Loquat leaves (Eriobotrya japonica) are an evergreen fruiting tree native to China and widely established across many tropical and temperate regions, including Indonesia, Sri Lanka, USA, and South America. Their thin but fibrous structure softens quickly in water, making them an ideal feeder botanical for shrimp, snails, and rasping fish in botanical method aquariums. Their rich mineral content and a broad spectrum of polyphenols benefit grazers within the aquarium while contributing ecological benefits to botanical method, blackwater, and biotope aquariums.

Loquat Leaves for Aquariums & Vivariums
Loquat leaves contain a wide range of minerals, which categorize them as an ideal food source within botanical method, blackwater, and biotope aquariums. Their tissues contain potassium, calcium, magnesium, and trace iron, benefiting shrimp, snails, and small grazing fish as the leaves soften and become colonized by fungi and biofilms, which aid in their digestion. Biofilms form quickly along their surface, attracting microfauna and creating an early-stage feeding zone that benefits nano species and juvenile fishes.
As the leaves break down, they contribute a dark detrital layer that supports a diverse microbial substrate community. Their polyphenol composition—particularly rutin, epicatechin, and procyanidins—offers mild antioxidant properties that can help stabilize stressed aquarium inhabitants. This makes them a helpful addition for betta sororities, ram fry, and shrimp colonies that rely on consistent access to natural forage.
Their rapid decomposition makes them ideal for establishing natural substrate beds in small and mid-sized aquariums, helping maintain the “perpetual substrate” which supports ecological diversity within the aquarium.
Beneath the Leaves: Eriobotrya japonica in the Wild
In their native range, loquat trees grow along hillsides, man-made orchards, and evergreen thickets, dropping firm, leathery leaves that settle into loose mats around the roots. Seasonal rains soften these leaves, feeding soil microbes and invertebrates that thrive among the litter. Birds, insects, and small mammals take advantage of their fruits while the fallen leaves create rich mulch and microhabitats where decay fuels the surrounding ecosystem—letting Mother Nature lead the way.
Sustainability Note:
This product’s packaging is home compostable.
Just like the botanicals inside, it will break down naturally and return to the soil because what supports your ecosystem should minimally impact our planet.
Not for human consumption. Preparation required.
This is a natural product—variation in color, shape, and texture is expected.

Home is getting more natural
While the aesthetic appeal of botanicals and tinted water can be quite attractive to us, the recreation of nature to emulate water conditions, feeding patterns, spawning displays, and territory building are the true benefits botanicals provide to our critters.
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.
