I’ve caught 2 - 4cm juvies in Ellen brook before. Usually hiding in long vegetation.
Not sure that pygmys would survive hungry nightfish as they get bigger but if they grow up with them they might not be so inclined to view them as food.
Just use a little scoop net and sweep in through the vegetation.

Nightfish are widely distributed across southwest WA, but within Perth, they're restricted to the upper reaches of rivers, think the Hills, or as malawiman85 said, the Ellen Brook area. I'm not too familiar with the Dawesville area, check it out this snazzy little website (http://freshwater.fish.wa.gov.au/) . Juveniles are in abundance around spring, you'll catch more fish at night, by sweeping a scoop net through vegetation. Down south, they're quite common, especially in seasonal pools that dry out in summer, those pools are full of other native fish species too. I headed down south not too long ago and the pools at one site were full of baby nightfish. Unfortunately, most of them died on the way home, which is weird, because they usually handle transport well.
I've caught nightfish in the Moore and Canning rivers, plus a few more down spots south.
In regards to your tank, a large nightfish (they can get up to 15cm in length) will definitely eat your pygmy perch and also galaxias around the same length as the nightfish. I'd say a 1m tank is ideal only for a small group of nightfish in the long term. They'll eat anything smaller than themselves, including fish, shrimp and moulting crayfish, and anything bigger than themselves will be too big for the tank you have. A 6ft tank would be a perfect sized predator tank for nightfish and also large galaxias, a 4ft tank is also feasible but might be pushing it, in my opinion. Also, galaxias will get too big for a 1 meter tank, I'd say 4ft is ideal for small to medium sized galaxias up to 10cm long. They'll reach 15-20cm when fully grown. Galaxiella sp. are another kind of galaxiid that are much smaller than Galaxias sp. and will definitely go in a 1m tank with pygmy perch, no problem. Only problem is that they'd be wiped out by a single nightfish. Plus they're illegal to take from the wild, but that's another can of worms
Good luck catching them

Galaxiella munda is found between Margaret River and Two Peoples Bay, in shallow streams and occasionally seasonal pools. An outlier population exists in the Moore River. They're a little difficult to catch, you'll have to sit there and watch for them, once you see them before you swipe at them with your net.
Galaxiella nigrostriata is found between Augusta and Walpole, with outlier populations in several locations. They occur almost exclusively seasonal swamps and pools. In small enough pools, they can be caught by driving a fine net through, and depending on the time of year, you'll catch loads. Otherwise, use the same technique as G. munda.
Both species only live between 12 to 24 months and require soft, acidic water, tap-water isn't recommended. As they are both threatened species, not only will you need to be cautious of rangers but also justify your illegal fishing by trying to breed them once you get them home

Definitely wouldn't be allowed to sell, they're both endangered and wild caught. Breeding them is encouraged though.

To be honest unless you're very experienced with keeping fragile natives that are very fussy with water quality I wouldn't entertain the idea of taking them from the wild. Its not only illegal but you'll probably end up killing them which just sucks for everyone, most of all the fish.

I won't catch any than since I don't have any experience with keeping them and I don't want to accidentally kill emSpeaking from experience, I agree.

If anyone can send me a link to how to care for them that I could study, i would really appreciate it. I'm building I large pond and if I could keep them with no problems than I would love to stock it with some since they are pretty cool fish

Info is scarce, since they are rarely kept.

I never caught a heap of Pygmys there but always a few. When the nightfish spawn, you tend not to see many mosquitofish. Presumably the nightfish fry start preying on the Gambusia fry in the shallow vegetation.
Best bet is to have a crack around spring time.
