25 Pack of Scuds (Amphipods)

Live Scud Starter Culture – 25+ Freshwater Amphipods

Tiny Crustaceans. Serious Ecosystem Energy.

Some aquarium inhabitants exist purely to look pretty.

Scuds have jobs.

These energetic freshwater amphipods spend their days grazing on biofilm, soft algae, leftover food and decaying organic matter—while also providing fish with the kind of natural hunting enrichment that frozen cubes simply cannot recreate.

Each starter culture contains 25+ live scuds, carefully packed and ready to establish in a separate culture container, refugium, planted aquarium or suitable bioactive aquatic setup.

Small? Absolutely.

Unimportant? Not even slightly.

Why Aquarists Love Scuds

A Renewable Source of Live Food

Instead of purchasing live food every few weeks, establish your own breeding colony and harvest scuds as required.

Fish instinctively chase, stalk and hunt them, encouraging natural feeding behaviour while providing a varied source of live nutrition.

Excellent for many:

• Bettas

• Gouramis

• Rainbowfish

• Livebearers

• Cichlids

• Loaches

• Larger tetras

• Predatory nano fish

• Newts and other suitable aquatic animals

Please research compatibility before feeding or introducing scuds directly into an aquarium.

Natural Grazers and Detritus Feeders

Scuds spend much of their time investigating surfaces for edible material.

They may consume:

• Biofilm

• Soft algae

• Decaying plant matter

• Leftover fish food

• Organic debris

• Microorganisms growing throughout the aquarium

They are not a magical replacement for maintenance—because apparently even tiny aquatic employees have boundaries—but they can become a valuable part of a balanced ecosystem.

Natural Enrichment for Fish

Watching fish hunt live prey is completely different from watching them wait beneath the feeding hatch like impatient customers at a drive-through.

Scuds encourage movement, exploration and natural predatory behaviour, helping transform feeding time into genuine enrichment.

Easy to Culture

Scuds are hardy, adaptable and capable of reproducing quickly when provided with suitable conditions.

A simple culture can be maintained using:

• A small aquarium or food-safe container

• Dechlorinated freshwater

• Gentle aeration

• Leaf litter, moss or porous media

• Moderate lighting

• Small amounts of fish food, vegetables or botanical material

Once the colony becomes established, scuds can be harvested periodically while the remaining population continues to reproduce.

What You Will Receive

Your order includes:

• 25+ live freshwater scuds

• A mixed selection of sizes where available

• Enough animals to begin establishing a starter colony

• Natural culture material may be included to provide shelter during transport

Because these are living organisms, exact sizes, colours and age ratios will naturally vary.

Nature does not manufacture identical inventory batches, and frankly, that is part of the appeal.

Recommended Uses

Scuds are ideal for:

• Establishing a renewable live-food culture

• Providing natural fish enrichment

• Feeding predatory or omnivorous aquarium species

• Adding biodiversity to suitable planted systems

• Refugiums and protected breeding areas

• Bioactive aquatic ecosystems

• Supporting the breakdown of organic material

For the most reliable long-term supply, we recommend culturing them separately before feeding small portions to your fish.

Introducing the entire colony into a fish-filled aquarium may result in what scientists technically refer to as “an immediate buffet.”

Important Compatibility Information

Scuds can be useful grazers, but they are also opportunistic omnivores.

When food is limited, some species may nibble delicate plants, mosses, eggs, weakened livestock or freshly moulted invertebrates. They may also be eaten rapidly by fish.

We recommend:

• Maintaining a separate breeding culture

• Avoiding direct introduction into sensitive shrimp-breeding tanks

• Providing adequate food and shelter

• Monitoring their population in planted aquariums

• Researching compatibility with your livestock

Scuds are best treated as a versatile live-food culture and ecosystem organism—not as a guaranteed solution for every aquarium.

Basic Culture Guide

Place the scuds into a cycled container containing dechlorinated freshwater.

Add moss, leaf litter, sponge media or other textured materials to create grazing surfaces and hiding places.

Feed lightly with foods such as:

• Algae wafers

• Fish flakes

• Blanched vegetables

• Dried leaves

• Small amounts of protein-rich fish food

Avoid overfeeding. Excess food can reduce water quality far faster than the scuds can process it.

Perform occasional partial water changes and avoid sudden changes in temperature or water chemistry.

Under suitable conditions, your starter culture can grow into a productive colony providing ongoing live food for your aquarium.

The Small Creature Your Aquarium Did Not Know It Needed

A scud culture is more than a bag of tiny crustaceans.

It is a renewable feeding system, an enrichment tool, a colony of determined little grazers and a fascinating miniature ecosystem in its own right.

They clean.

They breed.

They become snacks.

It is not a glamorous career path, but it is an extremely useful one.

Start your own colony with 25+ live freshwater scuds and bring a little more movement, biodiversity and natural behaviour into your aquatic world.
