Finally getting around to posting the rest of the field trip pics and videos. Next up is the Mulgrave River, located near to Bob's place. in fact, Bob and I walked to this location from his place. This is a shallow section where the red Valisneria occurs, with some other plants. Bob and I also found some nerites (Neritina pulligera) and the ever-present Stenomelania denisoniensis snails (grey foot colour variant). Water parameters were: pH: 7.0 - 7.1 GH: < 20 ppm KH: 10 - 20 ppm Temp: 22.5*C TDS: 29 The water in this section was around a foot to max. 1 metre. The red val Found the Stenomelania snails near the waters edge We first noticed the nerites by spotting their egg cases which were everywhere when we started looking. They were in the areas away from the plants, plenty of rocks (not sand) and a bit of timber and leaf litter. We found the nerites by turning over rocks, they were generally underneath, but occasionally not. The best way to tell where they were was to spot the white eggs (newly laid). The eggs turn yellowish with age. Also found a freshwater sponge under the rocks in this area Video of the nerites' habitat There were also a few Mulgrave gudgeons hanging out in this area We then moved downstream slightly to where the water ranged in depth from 1 metre to 2.5 metres. I apologise for the bumpy filming but I was fighting a swift current.

These are some shots from Little Mulgrave, a tributary of the Mulgrave River (near Cairns Australia). Enjoy. Water parameters were: pH 7.0 - 7.1 GH: < 20 ppm KH: < 20ppm Temp 22.5 TDS 29 Crystal clear water. 'Red' Vallisneria - It's a deeper red in other places further downstream in the Mulgrave, and I'll post those shots soon. Here is the natural habitat of a submerse growing fern which we believe is identical to one which was being sold on another forum for serious money. Bob and I will be putting some up for sale soon, if not into the August auction. Finally a couple of pictures of an interesting organism that totally fooled me into thinking it was a snail. Bob knew better and correctly pointed out it was the home of an insect larvae. Amazing engineering to create the snail shape using grains of sand.
