Seachem Fish Net Coarse Mesh 5

Seachem Fish Net 5 Inch is a practical aquarium net designed for catching, guiding, and transferring small to medium-sized fish during routine aquarium care. Its standard mesh allows water to pass through efficiently, helping the net move through the aquarium with less resistance than a fine-mesh net.

The approximately 5-by-4-inch net opening provides a useful balance of control and maneuverability for community aquariums, quarantine tanks, breeding systems, and everyday maintenance. Its standard 12-inch handle offers convenient reach for most home aquarium setups.

How to Use

Move the net slowly through the aquarium and gently guide the fish toward the net opening. Avoid rapidly chasing fish because repeated pursuit can increase stress and the risk of injury.

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

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

Fish-Handling Tips

  • Use slow, controlled movements when approaching fish
  • Guide fish toward the net instead of repeatedly chasing them
  • Avoid pinning fish against aquarium glass or decorations
  • Do not drag the net across sharp rocks, driftwood, or equipment
  • Lower the aquarium water level when necessary to improve control
  • Use a specimen container for fish requiring full-body water support
  • Keep fish out of the water for as little time as possible
  • Cover transfer containers to prevent jumping

Standard Mesh vs. Fine Mesh

Standard mesh generally creates less resistance as the net moves through the water. This can make it useful for active fish, routine aquarium maintenance, and removing floating debris.

Fine mesh has smaller openings and may provide more support for delicate fish, long fins, fry, shrimp, and other small livestock. Seachem offers a separate 5-inch fine-mesh version for more delicate species.

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 water, algae, parasites, bacteria, and other contaminants between systems. Dedicated nets are recommended for quarantine, hospital, breeding, 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

Select a net based on the fish’s body size, fin shape, behavior, and physical features. Fish with long fins, sharp spines, armored bodies, or delicate scales may require a fine-mesh net, specimen container, or another supported transfer method.

A 5-inch net is suitable for many small to medium-sized aquarium fish but should not be used to lift fish that are too large or heavy for the net. Choose a larger net or container transfer when necessary.
