How do you catch small tropical river gobies?

[Cichlid king]

I've tried just about every method, but these gobies are just uncatchable. I'm referring to these species:

Awaous banana:

Ctenogobius pseudofasciatus:

Sicydium plumieri:

Sicydium punctatum:

All of these species live in extremely fast flowing streams, and they're most abundant in rainforest type areas. I've tried to catch them with large nets, fish traps etc, but to no avail. Any tips? They're extremely fast, and very agile. They're also very slimey, so slimey that they can fit in tiny cracks. To catch them, I bought myself a small fish net, like this:

They live in streams like these:

Set up a seine net downstream from you across the the stream and then splash as much as possible going towards the net. Thatll scare fish into your net.

Tried it. None of them enterred it. They actually went up stream. They're quick little fish.

get to an area about 8" or more deep. put your net under some gravel in a well populated area and leave it there for about five minutes. granted that your handle is long enough some should be sitting on top the net or you could scare them into it. just lift the net straight up very quickly rocks and all.

best advice i got lol. it has worked for me.

Then get a friend to be behind you and both of you get big sticks and start splashing so there is less chance of escape also putting slack in the net would help.

put food or bait in a small ur let which hopefully has a long handle. when fish goes to eat it, u just lift and scoop up the fish

get a #15 (very very small) and put a little bit of squid or somthing

Casting net should work. stand back throw retrieve. run around 30 bucks.

As for the car battery wouldnt work. 12 volts DC is not ear enough to stun fish. Try a hand held stun gun solder probes in drop in the water and depress trigger. Works like a charm.
