Mulberry Leaves | Morus alba
Product Description: Sri Lankan Mulberry Leaves (Morus alba) complement our Nettle Leaves as a highly nutritious consumable 'feeder' botanical in the aquarium. They are not suited as an optimal leaf for building a leaf litter bed, as their palatability means they will break down easily in the aquarium. We coin these as 'feeder botanicals', as their primary role is to be consumed. Our mulberry leaves provide the necessary calcium, potassium, carbohydrates, and antioxidants to help your crustaceans build strong exoskeletons and molt more successfully. They can be fed alongside your weekly rotation of foods.
Ours are hand collected, rinsed, and air dried - never sprayed with any chemicals and are dang near organic. Preparation is not required, but we recommend rinsing them in hot tap water to help soften their tissues and allow them to sink more quickly. This bag and its contents are biodegradable! Did you know our product packaging is made from renewable and sustainable sugarcane? So just like the botanicals inside, it will compost when returned to nature.
Not for Human Consumption.
Quantities: 20c Sri Lankan Mulberry Leaves. Due to their fragile nature, we do our best to include enough to reconstruct 20 whole leaves when a whole leaf is not available. Your shrimp, snails, and other crustaceans love them just the same.
Aquarium Botanical Location: Sri Lanka.

Home is getting a bit 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.
