I decided I wanted to try to have a CRS colony more than to try breeding GBRs so I converted my planted GBR tank into a moss CRS tank. After a little over a week of tank preparation, I added 8 CRS (supposed to be SS grade) to the tank this morning. A huge thank you to Shrimpy Daddy who has been kind enough to answer my million and one questions as well as getting my order of SD products to me extremely quickly. I have high confidence that my new shrimp will be happy in their home because of his help. I probably should have let them settle in a bit more before taking pictures but I couldn't help myself. Below are shots of five of the eight shrimp. The other three didn't feel like posing for me. Can anyone sex any of these shrimp? I think they look great especially considering that they were put in the tank only a few hours ago. I would love to hear your opinions though. This is the first time I have seen CRS in person. I probably would be impressed with them regardless of their grade.

I have Ceratophyllum in my ponds and its my plant of choice for floating in breeding tanks and there is some in my shrimp tanks too. It does have this scary ability ni low TDS water to be shocked into losing all its needles and what a mess that makes! This week I sold a few shrimp and to hold lots after sorting for sale I put them in coffee jars with some horwort and bubbler... in the morning I had bare stems and shrimp in amongst needles... what a mess. Had to pick all the shrimp out one by one to bag them. So yes. What is it with Ceratophyllum? Michael I really like your automated changer setup.

It will also loose its needles after a peroxide dip, about 48 hrs afterwards. Dont ask me how I know......

Congratulations wot_fan....... Crs are awesome they are the ones that hooked most of us into this crazy life.And are still really my favourites always so active!...but I love all my shrimp! All those pictured are ss grade and I spot 3 females .....although you can never be sure from 1 picture. Look forward to updates..... Remember they are more sensitive them cherrys(rillis). So make sure you keep you parameters stable try not to fiddle too much and keep your regular wAter changes up. With shrimp daddy as your mentor you will be in safe hands.

I prefer java fern for this type of thing, absolutely bullet proof.

Yeah I have plans in the works for 'Fishmosy's zebra biotope tank Mark II'.

I can confirm that CRS shrimplets a pretty cool and I am sure with Shrimpy Daddy's advise you'll have a very nice colony soon. Soon you'll want to try Tb's and PRLs lol

I did mine with black poly and was a bit skeptical at first and expected there to be air leaks but its turned out very nice and definately no leaks. I did mine with threaded barbs (thread into the main line) and then use barbed inline taps separately that I locate just above the lid of each tank. I am very careful not to overtighten and strip the threads when insalling barbs. I used saddle clamps every metre to hold it to the wall and keep it neat. I bent the line around the corners rather than using an elbow fittings so it was a continuous loop without any breaks that could leak. The only reason I didnt use PVC was because I thought tapping each thread would be a pain - but Bob,s idea using a cordless with a screw shaft (or a tap for that matter) would make that task very easy. I'd consider PVC next time just for the neater look. Back to poly.. Bunnings do sell a white Holman branded poly in 13mm which is OK for smaller rooms or if just doing a rack. Anything big you'd want larger pipe. On my rack which has massive I beams I ran a line under each beam and attached it with electricians cable clips designed to hold cables to I beams. Photo below has an air line under the back beam, and a water line for continuous drip under the front beam. (sorry for the black on black!). The air droppers are regular silicon air line. The water droppers are black 4mm PVC irrigation line. This difference is only so I dont get them confused and spray water everywhere (any more than normal!)

Be careful of where you Yabby's come from, some don't take cold well, some of the ones from up here wont take cold, so just be careful. That is a pink form red claw I had and that one did not take cold, there is also a blood red form of Cherax depressus that wont take cold, if its from your way it should be AOK Bob

Fantastic! My enjoyment is to take photos that provide enjoyment for others. I just got some new camera equipment in the mail yesterday that I believe will help me take some nicer photos so I cannot wait to find some free time to try it out. The blue bolts are nice, I agree. They’re definitely more photogenic than my other shrimps. Correct, the last two photos shows my Red TB tank. I usually don’t take photos of shrimps inside this tank because the lighting is always really poor, but my new flash extension arm will allow me to mount the flash in a more ideal spot to take better photos. The Red TB tank is really small, 8gals, and it’s hard to get the flash on the tank. But now that I have the extension arm I can mount the flash and better light the tank for photos. The tank has a few Red Bolts, as you can see. I need to cull these and put them into a dedicated tank and breed for the colors. I would say they are more pinkish than they a are red. I’m still observing to see if these “red bolts” are actually a new thing or just crappy goldens resulting for years of mixing. Anyone with more information on red bolts please chime in. Anyways, I’ll definitely devote more time to taking photos of the Red TB now that I have the proper equipment, so stay tuned!

Yevy has started something here with that yabby thread! You should both be able to just go catch a yabby, and so should anyone else in this country who wants one. I suggest an ordinary bait trap into a farm dam, municipal lake or often aqueducts have them too. Failing that, most fishing shops sell live yabbies as bait and occasionally aquarium shops sell them too. If grown up from small in good clean water most yabbies will be blue. Bait the trap with aquarium food. I often recommend Aquagreen as a supplier but in this case I don't. Dave sells quadricarinatus and bicarinatus, both tropical species. You guys want cold tolerant southern species, destructor if that's still the right name. I think it got broken up. BTW if you buy from an aquarium you may encounter the same problem, ie quadricarinatus sold as a normal yabby. Best to catch them, locally if you can. Crabs - yabbies will be better outside than RCS, won't need heating as Will suggests and will probably work out ok with small shrimp as Yevy's post shows. They may not get along with other yabbies however. They're soft just after moulting and prone to attacks. Similar with fish, if the fish are decent sized they may eat the yabby after moulting, if they're smaller they might become food. Believe me the yabby will be happy to eat a fish, just a matter of time till one ends up caught. Spotted Blue Eyes are lovely fish and Dave's form is a nice one. They won't go in cold water but might not damage a shrimp population too much in a tank. Threadfin Rainbows are probably less of a threat to shrimp though.
