How to remove a fish

[Liam's tank]

I need to remove a Starry Blenny from my tank. He has outgrown it and is becoming a problem. Any ideas on how to catch him without having to rip my aquascape apart?

There are 4 options available:
1. Do nothing.
2. Fish trap, but you'll often catch him last if at all... Murphy's/Sod's law and all that.
3. Lower the water level to where his swimming lane is eliminated and bam one caught fish.
4. Worm and a hook.

In my experience I rather try to catch smoke with a fan then a fish in an established tank.

Yeah if tank is not very big I'd drain water into a bucket or what ever large enough.
I have 400 gallon tank and I had to catch dwarf angels out of My tank. I ordered a small 500gallon pool on Amazon and installed it in garage just to drain water into to catch them. Some corals where exposed to air for like 30 minutes. But I was constantly purring water on them until I filled the tank back up.
Only other problem with this, if fish usually have a hiding hole. It will stay in it even if water is drained out of tank. And its just as hard to get the fish out of the cave/hole.

Good thing i was doing a tank teardown, cause I literally had to remove every rock and feel for my yellow watchman goby.

Lowering the water as low as possible is the easiest way, might have to pull some rocks though, depends on the aquascape and tank size.
Tank dividers help too, but again depends on the tank size, obviously smaller is easier.
