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.

Also coming from the Mulgrave is a gold variant of Stenomelania denisoniensis, with either gold spots on black or a completely gold foot. We have named this variant S. denisoniensis "Mulgrave Gold". This is the variant Bob has alluded to on the forum a couple of times recently. However we are not certain whether it breeds true, and whether the colour will be maintained in aquaria. So far, mine are generally holding colour but don't have the same impact as the colouration they had in the wild. Here is some shots of them in their natural habitat and in my tank. Finally some shots of a cheeky fish way downstream

1 pointI thought H2O was good for plants? Bloody di-hydrogen oxide. Terrible stuff. One of the most effective solvents in the world....... ..... Maybe you mean H2O2 ?1 point

1 pointI use super glue gel. It gives you a bit of extra time to move the plant into the right position. Only problem with super glue is it tends to dry white so you need to cover it with the plant or a bit of moss. All my early driftwood creations were done with super glue. Now I prefer nylon fishing line but the glue is very good.1 point -
1 pointCaddisfly larvae has two different stages of larvae. The fact that there is a silk like thread cocoon I would say that it is definately it. I would be confident that it came in on the plant in egg stage and that is why it has taken so long to show up . You can use what GC has mentioned or you can use condy's crystal I had to buy mine of ebay. It's hard to get know.1 point

1 pointIt could be three things that I can think of. Dragonfly Nymph Deadly to shrimp Caddisfly Larvae mainly feeds on plants but can also kill shrimp.....Look for silk threads on leaf on underside Midge Mainly a leaf eater I cant say for sure but I have checked my freshwater insect reference and I think Caddisfly larvae personally because in second photo it looks like a silk type cacoon I would be checking because if there is one there could be more. Have you added new plants a cpouple of months ago. it is possible it came in on the plants as eggs. You may need to remove plants and treat. I would also be having a good look on substrate rocks etc for more. Hope this helps.1 point
