I have available some Silver-lined mudskippers (Periophthalmus argentilineatus), 5-7cm in length. They were wild collected from Carnarvon and already accept frozen bloodworms and live earthworms.

Although they are hardy, please bear in mind the specialised setup mudskippers require. Mud is absolutely essential, while sand, gravel, bare bottom or others will not suffice. They require humid air and a cover over the tank to maintain this, as well as to prevent escapes. They require a mostly terrestrial setup and will drown in a fully aquatic setup. Tidal simulations are ideal and recommended. This species in particular can be very aggressive to each other, and best kept alone or in a very small group, i.e. 1-2 individuals in a 3ft tank, or perhaps 3-5 in a 5-6ft tank, bear in mind just how much mud you'll need if you want a larger setup.

If you're interested, please show me that you have an appropriate setup ready for them, they weren't easy to get and they're not easy to keep either. I want to be sure they're going to a good home.

PM if interested.

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.

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.

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.

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

PASES Aqua in Cockburn currently has 5-7cm juvies for $20 each.
