How to Use

Move the net slowly through the aquarium and gently guide the fish, shrimp, or other livestock toward the net opening. Avoid fast movements or repeated chasing because excessive pursuit can increase stress and the risk of injury.

When possible, use a specimen container, aquarium decoration, or second net to calmly guide livestock. Once the animal enters the net, keep the transfer distance short and move it promptly into the prepared aquarium or container.

After use, rinse the net thoroughly with clean water and allow it to air dry completely before storage.

Handling Tips

  • Use slow, controlled movements when approaching livestock
  • Guide animals toward the net rather than repeatedly chasing them
  • Avoid pinning fish or shrimp against aquarium glass or decorations
  • Do not drag the net across sharp rocks, wood, or equipment
  • Inspect the mesh for tears before handling fry or shrimp
  • Use a specimen container for animals requiring full-body water support
  • Keep livestock out of the water for as little time as possible
  • Cover transfer containers to help prevent fish from jumping

Fine Mesh vs. Standard Mesh

Fine mesh has smaller openings and provides more support for delicate fish, fry, shrimp, long fins, and other small aquarium livestock. Seachem recommends its fine-mesh nets for more delicate species.

Fine mesh may create more resistance while moving through the water than standard mesh, so slow and controlled movements are recommended. Standard mesh may be preferable for active fish or general debris removal because water can pass through it more quickly.

Using the Net for Shrimp and Fry

The small opening and fine mesh make this net useful for carefully transferring many freshwater shrimp and fish fry. Always inspect the net before use because very small livestock may escape through damaged or stretched mesh.

Avoid leaving shrimp or fry inside the net longer than necessary. Transfer them promptly into a prepared container containing suitable aquarium water.

Cleaning & Storage

Rinse the net thoroughly after every use to remove aquarium water, debris, algae, and organic material. After using the net in a saltwater aquarium, rinse it with freshwater before allowing it to dry.

Store the net in a clean, dry area away from aquarium chemicals, direct heat, and sharp objects. Inspect the mesh, frame, and handle regularly and replace the net if it becomes torn, bent, loose, or damaged.

Cross-Contamination Note

Using the same net in multiple aquariums can transfer aquarium water, algae, parasites, bacteria, and other contaminants between systems. Dedicated nets are recommended for quarantine, hospital, breeding, shrimp, and retail aquarium systems whenever possible.

If a net must be shared between aquariums, clean and disinfect it using an aquarium-appropriate procedure. Rinse it thoroughly and allow it to dry completely before reuse. Never place a net containing cleaner or disinfectant residue into an aquarium.

Important Aquarium Care Note

The fine mesh helps support delicate livestock, but careful handling is still necessary. Select a net based on the animal’s body size, fin shape, behavior, and physical features.

A 3-inch net is intended for small aquarium livestock and precise handling. It should not be used for fish that are too large or heavy for the opening. Choose a larger net or supported container transfer when necessary.
