Looks like the bullrout to me too.
Have to find it and remove from tank.
Cheers

From what Ive read its basically a freshwater rockfish, they grow quite ugly and spikey unfortunately. Quite a glamorous juvenile though.

Hmm a fisheries expert just told me that it was a Purple-Spotted Gudgeon.

They look almost identical

Yea they do. Not sure now. Id probably trust the fisheries guy.

Can those fish cross breed? In Florida we have a lot of different types of pan fish that look exactly the same when they are young only to grow into whatever is the dominant gene. For example, I have a lot of what I call bluegill hybrids in my AP setup. Most of them have a blue spot on the back of their gills (Blue Gills). Some have the blue spot and red/orange underbellys (Red Breasted Sunfish crossed with Blue Gill). Others have a stripes similiar to Blue Gill but a blood red stripe in their eyes and a large mouth (Warmouth Bass - which is actually a pan fish, but are possibly a cross between largemouth bass and pan fish, who knows). Just sayting that you both could be right in a way.

That first pic looks nothing like a bull rout (fresh water stonefish). I have caught quite a few of the over the years in bait traps in a few different river systems in south east Qld.
Also have been fishing with a mate who stood on one early one morning, by the way he was carying on it looked pretty painfull. I dont think you would have it in your hand for very long.

I always wear shoes when I'm wading these days.

Now that one does look nasty

Looks like one of your Jades Mantis

I deserved that
