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.

First up the tank my Blackmores are living and breeding in, they share it with a couple of Darwin Red Nose, Chameleons, at least one Darwin Algea Shrimp, a growing school of spotted blue eyes and a few hundred snails. The log dominates the tank and all the shrimp take full advantage of the dark recesses of it. Most of the above pictures are of juvi or sub adult shrimp.
