I keep and breed Cherry shrimp in the red and wild forms in water with a PH slightly under 6. They are thriving ! I have over 200 but its hard to count that many they wont stay still. I have Amano shrimp to my first Amano is three years old.
Calcium is very important. I feed them on Hakiri Crab pellets and other food hight in Calcium like spinich. If the diet is good the water can stay at a low PH with no problems. I have some crushed oyster shell in my filter but I think this makes less diference than the food as they were fine for months before I put it in
Hope this helps. Shrimp are great fun and will eat your algea too !
So you reckon that just by adding the calcium they should be fine? My other concern is that I was hoping to house them in with some angel fish. They are quite small at the moment but Im unsure about whether or not the shrimp will be eaten when the fish grow a bit. Would they be safe in there with them or would it be best to just put them in a tank on their own?
EagleC, I live up in Scotland and my tap water is very soft and slightly acid. GH and KH both virtually 0 and my pH is 6.6 straight from the tap. To lower the pH you could mix RO water and tap water 50/50 when you put fresh water into your tank when you do a water change. Another alternative that Ive read about is whats called a 'peat sandwich' which involves putting a small amount of peat into a stocking and placing this into your filter with all your other media. I don't know how well this would work but it maybe worth a try? Someone with more experience will be able to help though, as I say, Im just lucky with where I live!
Ask some of the members from London how they lower pH as I think they have very hard water down there?
With a PH that low you're quite lucky in the fact you can keep crystal red shrimp....I saw some fine specimens in my lfs, grade A's with one that had the nicest white saddle i've ever seen. I couldn't buy them because i've tried a couple of these shrimp before and they don't last long in my tanks although my tigers are thriving big time yet these are also meant to be delicate like CRS. You could also keep bumblebee shrimp but there's a chance they will interbreed with CRS and bee shrimp will for certain. Red cherry shrimp are another option but avoid species that prefer higher PH's like green shrimp (caridina babaulti).
If you were going to go for crystal reds it would be worth setting up a shrimp only tank due to the cost of the shrimp which you could breed and possibly sell....espcially if the shrimp are quite rare where you live. Also you'll get to see the shrimp so much more if fish aren't around and they'll be less waste in the tank (high nitrates are a no-no with shrimp). My tigers have their own tank and I have so many....around 7 or 8 generations of shrimp.
Actually I was asking boatboyy as he said his water was <6ph. I use RO but even with that the water is Ph 6.4 minimum. By the time I've added the Gh minerals the Kh is also increased and I end up with 6.8-7.0 This isn't causing me any problems tbh as thats about what I want but I'm still interested in how you could accomplish more extreme conditions should I want to in future.
Are crystal reds harder to look after than other shrimps? I have absolutely no idea with these animals so I wouldnt want to start off with something too difficult.
I have a spare 120L tank that I could use, what kind of stocking density would I be looking at for this? Also, sourcing ANY shrimp up here is difficult (my LFS says they sell like hot cakes but they rarely have them in stock?!) so is there a reputable online store where I could maybe pick some up from?
