A handle that reaches the far corner.
Fine soft mesh matters more than the size. Coarse netting catches fin rays, and the long fins of a betta or a fancy guppy tear before you have lifted them clear of the aquarium.

Why you'll love it
Chasing a fish round a tank stresses it far more than the catch itself. A handle long enough to corner them cuts the whole business to a few seconds.
A coarse net snags the trailing fins on a betta or a fancy goldfish, and torn fins are how fin rot gets started. The weave here is tight enough to lift fry without catching.
Experienced keepers herd with a large net and catch with a small one. At this price it is worth buying both sizes rather than chasing round with a single net.
Good fit if
Look elsewhere if
The specification that matters is how fine and how soft the netting is. Coarse mesh snags fin rays, and the long trailing fins of bettas, fancy guppies and veiltail goldfish tear on it readily. A torn fin is an entry point for infection, so the net can cause the problem you were moving the fish to avoid.
Fine soft nylon avoids that. It also holds smaller fish and fry that would swim straight through a coarser weave, which is the other reason to have one. A rustproof coated frame matters because a corroding frame stains and eventually roughens, and a rough frame edge does the same damage as coarse mesh.
Chasing a fish around a tank is far more stressful than whatever you were moving it for, and a pursued fish will injure itself against hardscape. The technique that works is to hold the net still in one place and guide the fish into it with your other hand or a second net, rather than swiping.
Keep time out of water to a few seconds, and where you can, catch the fish in a container of water instead so it never leaves the water at all. That is the gentlest method for anything delicate, and a net is then used to guide rather than to lift.
The head should be comfortably wider than the fish it is catching. A net that a fish barely fits into requires precision you will not have with a moving target, and a net far too large is unwieldy in a planted tank and knocks hardscape over.
Four inches suits fry and small schooling fish, five is the sensible general purpose size, and six suits anything larger. If you keep a mixed community it is worth having two rather than compromising on one, since they cost very little.

The details
| Head | Suits | Notes |
|---|---|---|
| 4 inch | Fry, neons, small rasboras | Fine enough to hold very small fish |
| 5 inch | General community fish | The sensible single net choice |
| 6 inch | Goldfish, larger cichlids | Unwieldy in a heavily planted tank |
The head should be comfortably wider than the fish. A net a fish only just fits into needs precision you will not have with a moving target, and one far too large knocks hardscape over.
Rinse it in clean water after every use and hang it to dry by the loop rather than folding it into a drawer. A net stored damp goes stale, and a stiff net is a harsher net, which is exactly what you were avoiding by buying fine mesh.
Check the mesh for holes and the frame for rough spots before each use. A small hole is where a fry escapes and a rough frame is where a fin tears. Nets are cheap enough that replacing one at the first sign of damage is the right call.
Loved by real pet parents
Our tank is a metre long and the old net meant leaning right in every time. Extending the handle lets me work the far corner from the front, so nothing goes in the water but the net itself. Moving the fish into a bucket for a clean took under a minute instead of the usual pantomime.
The mesh is lovely and soft and it does not snag on the plants. My grumble is the telescopic section, which has twice slid back in on me while I was reaching across the tank. Tightening it firmly before you start sorts it, but you have to remember.
Using a big net to steer and a small one to catch is the advice I was given and it does work. The 4 inch slips between the plants without dragging them up and the 6 inch blocks the escape route. Both hang on their loops beside the tank.
Half of what I use it for is not catching fish at all, it is lifting bits of plant and the odd floating leaf off the top before they break down and cloud the water. The fine mesh picks up much smaller pieces than I expected it to.
Two of my old nets had orange bloom on the frame within a year. This one is coated and after nine months of being dunked twice a week it looks like the day I got it. The handle collapses down so it fits in the cupboard with the rest of the kit.
No issue with the netting, it is genuinely fine and soft. The bag of the net is quite shallow though, so a lively fish can flip back out over the rim before you get it to the surface. I manage, but I find myself cupping a hand over the top.
Moving three fish into a holding bucket while I cleaned the substrate used to be the worst part of the routine. With the handle out I can corner them against the glass without climbing into the tank. The whole job was done in twenty minutes.
I picked the blue one because it stands out on the shelf, and after about six months in a brightly lit tank the colour has gone patchy. It still catches perfectly well so this is purely cosmetic. If I ordered again I would take the green.
I use it in a shrimp tank mostly for lifting moulted shells and leftover food off the surface, and the weave is tight enough that nothing slips through. Being able to shorten the handle right down makes it manageable on a small tank too.
Good questions
Match it to the fish, not the tank. Four inch suits tetras, guppies and fry; six inch suits goldfish and larger community fish. If you keep both, buy both.
The mesh is fine enough not to snag, but the safest way to move a betta is to guide it into a cup rather than lift it out in a net at all.
Enough to work a standard home tank without wetting your sleeve. It is a light tool for catching, not for scrubbing, so do not lever gravel with it.
Four inch for fry and small schooling fish, five for general use, six for larger fish. The head should be comfortably wider than the fish, since precision is difficult with a moving target.
Fine soft mesh is the safest option, and this is that. For a betta specifically, catching it in a cup of water is gentler still, using the net only to guide it.
Enough to reach the back of a standard deep tank without putting your arm in. Extend it before you start rather than while a fish is already in the net.
