There are so many rivers to collect from and invariably the fish collected from each river are different in some way. For example gertrudae can be collected in many different waterways. But from one river to the next they may exhibit variations in colour
or size or length of finnage or in the size or quantity of spotting on the fins. The same holds true with what are known as trifasciata.
There are probably 30 or so - maybe one our Aussie members can be more accurate - colour variations of trifasciata alone. As you can imagine published photos of ALL of them would probably be quite difficult to assemble in one place. I'm sure you could do
it by buying back issues of Fishes of Sahul and any other rainbow literature that you could find. That could get expensive though!
There is a photo of Giddy river trifasciata in Leggett and Merrick's book " Australian Native Fishes for Aquariums". It's not a great photo and that is now a difficult book to get ahold of. Which kinda emphasizes my long winded point! :-)
Adrian Tappin's website " Home Of The Rainbowfish" has a great selection of photos that you can look at. Hopefully one day Gunther Schmida will have a website of his own and display the multitude of rainbow photos that he owns.
