Here are our picks and how to catch fish properly.

Key Takeaways

A fine, soft-mesh net catches fish without tearing delicate fins.
Two nets beat one — guide the fish into a held net rather than chasing.
For spiny catfish and loaches, use a container instead of a net.
Moving fish in a container of water is the least stressful method of all.

What to look for

Fine, soft mesh that won’t tear delicate fins.
The right size — big enough for the fish, small enough to manoeuvre.
A second net — two nets are far easier than chasing with one.

For spiny catfish like pictus and loaches, a solid container is safer than a net, which can snag their spines.

Our top picks

Best all-round — fine soft-mesh net. A fine soft-mesh net is gentle on fins and suits most community fish.

Best for delicate fish — fish-safe ‘catch cup’. A catch cup or trap avoids netting stress entirely — ideal for bettas and long-finned fish.

Best value — twin net set. A two-net set lets you guide a fish into the second net rather than chasing it.

The two-net technique

Chasing a fish around the tank stresses it and everyone else. Instead, hold one net still and use the second to gently guide the fish into it — patience beats speed. Better still, for moving fish between tanks, guide them into a container of water and lift that, so the fish never leaves the water. See acclimating fish.

Frequently asked questions

What is the best type of aquarium net?

A fine, soft-mesh net is best for most fish as it won't tear delicate fins. For delicate or long-finned fish, a catch cup avoids netting stress, and for spiny catfish a solid container is safer.

How do you catch a fish in an aquarium without stressing it?

Use two nets — hold one still and guide the fish into it with the second, rather than chasing. Better still, guide the fish into a container of water and lift that, so it never leaves the water.

Why shouldn't I use a net for catfish?

Spiny catfish and loaches can tangle their fin spines in net mesh, injuring themselves and damaging the net. Guide them into a rigid container of water instead.
