I know P. cyanodorsalis have no problem in full-strength marine and even hypersaline water, but what about other species like P. signifer?

Yep these guys are euryhaline, believed to be unnecessarily diadromous.

Found in estuaries and mangroves along pretty much the whole east coast... Their preference is definitely on the fresher side though.

Do they do more poorly in fully marine conditions? I was hoping to have some swimming around in my reef tank, but if they won't do too well, I might just have to find an alternative stocking choice.

Probably ok if you acclimate them carefully... who knows? like anything aquatic, sometimes it works, sometimes it doesn’t. Personally I don’t think they would add any value to a reef tank and are another nitrate source (small though it might be).

The general consensus seems to be yes, after a lot of asking around.

 

I reckon we don't see enough Australian native fish in marine tanks, especially reef tanks, nor are there any choices in terms of schooling fishes in saltwater that don't get huge, which is why I'd like to try keeping them in a reef tank.

 

Nitrates shouldn't be a problem, a protein skimmer, some macroalgae and big water changes take care of them.

Saw a butis in a reef tank a couple of years ago, belonged to another forum member.

They're great fish too. Would probably eat the Pseudomugil tho, there's not much I can put in a tank with predatory fish, except other similar-sized fish.
