Hey guys, new to the boards.
 
I've got natives too.  
 
Used to keep a Murray Cod back in Melbourne which was about 45-50cm long.
 
Had a short-finned eel for a while, which ate from my hands (the cod just tried to eat my hands instead).
 
Had a tandan too, which was great.  Grow really fast when you feed them properly.
 
At the moment, I have:
 
3 Empire gudgeons
7 Eastern rainbowfish
Approx. 20,000,000 fly-specked hardyheads (more like 50, really)
One jungle perch (Tojo), about 13cm long
1 Hyrtle's catfish
1 baby archerfish
 
Would love to be able to keep more, but I've only two tanks, with the bigger one pretty much devoted to Tojo and his living larder.  Wouldn't mind a bullrout or snakehead gudgeon one day though...
