Hello, Does anybody know where i can get some Zebra's? Thanks

A few months ago, I lost a lot of shrimps due to high temperature (around 32°C). So I decided to make an aquarium chiller for my nano (20L). My requirements were : - Noiseless - Able to reduce by 5-7°C a 20L aquarium - Economic electrically - Part of the canister filtration system (no visual inconvenience) - Not pricey (under 100$) - Shrimp compatible (no copper used) Becarefull : Aluminium is used to "exchange" the heat. It can be toxic if used in pH below 5.3 During my initial research, I found this interesting article : http://www.shine7.com/aquarium/chiller.htm I changed the peltier module used, here are the calculation : For a 400W Peltier, if I have 4.9V in input, and the local temperature is 32°C, the temperature of my 20L aquarium should be 24°C for 40W used. Here are all the needed parts : - Peltier module : TEC1-12726 (50x50mm 400W) around 20$US - Aluminium Water cooling block (76x68x8mm) I prefer this one over the classic 50mm one because it's bigger so better thermal exchange - 12V 240W Power supply (transform AC to DC) - 100W LED driver (0.8-28V output) (adjust the tension on the peltier module) - 2 Fan speed controllers (3A DC-DC step down converter) - 12V Thermostat (the chiller is working only when it needs to) - Heat sink (Noctua NH-D14) Based on http://www.frostytech.com/articleview.cfm?articleid=2789&page=4 , this heat sink is perfect - A 50x50mm copper sheet to make the connection between the heat sink and peltier module. The peltier is bigger than the heat sink base, so I thought it's better to have this sheet to reduce the heat of the Peltier - 6mm silicon pipe (it's the diameter of the water cooling block) - 6=>12 water pipe coupler - Thermal paste - Electrical cable All the parts together : The total cost is around 100$US (greatly depends on the heat sink, i bought mine 2nd hand) The final build : Just started to make some test, it's working perfectly! The only drawback is that it reduce the outflow of my canister filter. If you have any questions :)

It's bugging me that I don't know what these are.. They came in a very mixed batch of shrimp that included everything from CRS/CBS to full Taiwan Bees. They look like they could have been Golden Bees... except that they're very peach. I've not actually seen any confirmed Golden Bees in person, so they well could actually BE GB's. Any ideas or confirmation from GB owners? Sorry about the fuzziness. I stuck the post here because they sorta look the most like my (probably) Redbolts.

Next time I head out down that way I will get photos of the paperbark Wallum areas, I may even convince the other half to go for a drive north to some areas towards Marlborough that I have wanted to check out every time we head towards Mackay. I might have to use the "well I spent 14hrs (in one day) with you driving to Warwick for a pup...." card to get to go to my next excursion.

Sorry about the delay in this update but I have had some computer issues. Anyway we went out to Hedlow Creek this first photo is of some of the damage still laying about after cyclone Marcia, considering how flat this area of country is with just a couple of old volcano cores the wind must have really howled across the flats. One of the extinct volcano cores The lush green area in the front of the picture I think is called lake Mary but I am nut sure since it is also posted as private property. Another one of what I think is Lake Mary Much of the creek has private property signs posted along it, and the few places that apparently you are allowed to get in or near the water, the banks are steep and chopped up from cattle. There is also a pretty thick weed bed made up mostly of lilies to fight you way through if you are going to even try and dip netting for any fish, shrimp or snails. The water is also quite deep and no clear, even though I know people go canoeing and kayaking on the creek I am not that keen to become a croc snack. Hedlow Creek The thick weed at the waters edges Another volcano core From Heldow Creek we went on to Byfield area and stopped at a creek crossing at a place called Red Rock This area was very devoid of any aquatic plant life and even the few fish I saw where timid. I did net some gudgeons (and released once I knew they where gudgeons) there was also some rainbows and but they where far too timid and not in large numbers. The water was actually so devoid of obvious food sources that even a small eel emerged to eat the bits of bread I had tossed in as an attractant. And finally I saw some little sundews growing in the bank at the creek crossing After doing some further exploring down towards an area known as Stockyard point I think I may have finally found some likely paperbark swampy Wallum country that should house the local Rhadinocentrus species. But that will have to wait for another day. Another place I know of that may house Rhads is north of Rockhampton in the way to Mackay.
