What is this fish out of local creek in caboolture?

[Yodapwnsasmurf]

Firetail Gudgeon

[TED]

^^^^^^^^. they are slowly disappearing from our local waterways in my opinion. i use to catch them alot when i was a kid and didnt even get excited as they were so plentiful....

its the opposite these days. gorgeous little underated native gudgeon.

[AquaMaster]

its not an empire gudgeon>?

The fin colouration would indicate firetail gudgeon.

H.galii (Firetail gudgeon) is the best bet - but it could be a H.kluzingeri (Kluzinger's gudgeon - carp gudgeon) due to the double striping on the dorsal. To be honest, the carp gudgeons are a "complex" meaning that they could be definite species on the boundaries of their ranges, but overlap and are the "same" where they come together in the centre of their ranges.

And yes, they are an underrated little guy - first native I ever caught :-)

Disapearing ? Jeeze I have trapped all around the Noosa/gympie area looking for Rhads and usually all I find are Firetails, by the 1000's.

[TED]

they maybe abundant in some areas but i have noticed a massive decline locally. sheep station gully algester, and oxley creek algester.

im not saying they have disappeared but the numbers have been decimated for some reason.

im suspecting people using these fish as feeders and then wondering why they cant catch anymore after they have cleaned the local waterways out.

a friend i tried to educate about raping the system dry has been wondering where the fish have gone as he was feeding local caught fish to his barra.

he now spends $20 a week on feeder goldfish. i told him to try and get his barra onto pellets which i think he is trying to do.

on the plus side he did clean most off the swordyz out.

I agree with Ancalimon

Western Carp Gudgeon (H.kluzingeri)

and Unspecked hardyhead (Craterocephalus fulvus)

but maybe a fly speckled hardyhead(photo a bit blurred)

[Radical]

Looks like a Hardyhead

Carp gudgeon complex meaning naturally occurring hybrids and /or inadequate & useless classification system?

Most fish studies deal with population "groups" instead of species now. I wonder how long it will take until the swordtail can be called a native species? (Like the dingo).

Thankyou for the quick reply Id to all who helped

Cross reference with google research has confirmed SPeckled HARDY and Western Carp Gudeon confirmed

Are these both legal to keep otherwise back to the river they will go cheers

There fine

Once any fish has been in your tank, they shouldn't ever be released into the wild again, even if you know exactly what part if the river or lake they came from.

Regarding population "groups", I dunno about that (at least what I'm personally interested in, which is freshwater species of "Sahul" and Oceania). A complex is a fairly well established terminology in biology (Species complex - Wikipedia, the free encyclopedia). I would assume that while the government defines a swordtail as an exotic pest species, it'll remain that?

They should be both legal to keep. And also (as pointed out below), don't release fish that have been in your tanks back into the wild. You may inadvertently release something else that you don't know about (potentially a pathogen - but perhaps a plant or snail etc.).
