Have you had a look on here:-

https://skfaquatics.com/forum/forums/forum/40-shrimp-health-care/

I'm not aware of any books, most of the books on shrimps do seem to originate from Germany, though some have english and some other languages, but this usually makes it a big book with not much detail. 

Is there anything in particular that you need some advise on, or is it just a general question?

I've just helped a friend through giving advise on Ellobiopsaide that information is what I found here,this as been going on two weeks and the disease looks to be receding since this as gone on my interest in shrimp disease as been sparked, and as a paramedic this also interests me, and as you say very little is written in the form of a book, the one I found in Germany I've asked if theres an English version but dont hold up on any hope on that

I had a look on the wider web and there are a few books on shrimp diseases but they are really meant for breeders supplying the food industry and most were out of print at the moment anyway!

Are there enough diseases for a specialist book for shrimps? The ornamental shrimps are so small that personally, I doubt I would be able to tell unless there were dead bodies but my eye sight probably isn't 20/20 now.

Hopefully you may be able to get an english version of the book you did find at some stage and hopefully your friends shrimps will make a good recovery following your advice. If you can find it anywhere featured on the internet you could try google translate!

I think the germans are probably top of the tree with shrimps, as it must be big business out there, and they produce the most stuff for the hobby?

i agree disease amongst shrimp i so small it wouldn't warrant a book so perhaps i need to look for a book that integrates all shrimp and related disease, at present the best i can find is here on SKF which covers quite a lot and is quick and easy to access, thanks for the response anyway sdlBfanUK Didnt realise your not far from me

There were a couple of books I saw on amazon which covered 'fish and shrimps' but I imagine they were mostly fish diseases, and anyway they were out of print/stock.

Did you get some new crystal shrimps to try and improve the colour as per your post late last year?

I have just done my shrimp tank for this week! It is good to see others from the UK interested in the hobby!

I did get new stock and they started breeding fine and my lfs was selling them  at £7.50 each and it got to a point where my stock went down when that happened I decided to separate black bee they are in a 10gal  and have gone mad babies everywhere anyway for some reason my Crystal's have decided to stop breeding and I dont know why kh3 gh5 ph 6.5 temp 23c perhaps you can shed light on this, I've just started a super red crystal tank and I've manage to breed some black rose so have setup another tank for them on their own they have been in with black bee but the perameters need to be a bit higher

You're going to end up with a whole room full of tanks if you keep going.............

The only parameter that is a bit off in the above is the Kh3, which should be 0-1 but I am not expert enough to know whether that would actually stop crystal shrimp breeding. Are you using RO water with a buffering substrate with the crystals (I am guessing not with that Kh figure)? In my (limited) experience the caridina need the soil substrate and re-mineralised RO water, but the neocaridina are fine in tapwater and any substrate! If you check the Kh for the black bee shrimps and it is lower than the 3 of the reds then I guess you will know?

My Taiwan bees stopped breeding for about 3 months over the winter but have recently started again, but if your black bees are breeding, but your reds aren't I guess it can't be that, it has to be tank related?  If you want to keep neocaradina with caridina it is possible but you would need to set the parameters nearer caridina than neocaridina, as the caridina are a lot more delicate and particular when it comes to water.

There is this very good video on most of the shrimp basics which may help, each time I watch it I tend to have forgotten something!

i made a mistake there some how anyway decided to do the two tanks again and both read kh1 i do use flora base pro substrait in my tanke to buffer ph to 6.5 and have used ro water for a few years in all my shrimp tanks, up until last year i was keeping and breeding both caridina and neocaridina in the same tank but it was a fine line with the perameters so decided to split, it seems my small tanke take off and breed well but the crystals are in a 220ltr but if the water is good i dont know where else to look

That all sounds ok.

When I first decided to 'try again' with the taiwan bees I set up a 15L tank and bought about 10 various shrimps. About 3 months later I had about 100 babies, it was ridiculous really. I got and set up the 35L and transferred the shrimp but as with you have not had a great explosion in the bigger tank as I did with the smaller tank, though I am happy about that as there are enough as it is, and as the tank runs it probably stays at that level as it can't support any more, maximum occupancy?

Were the crystals red really young as I believe they have to be 6 months before they can breed, whereas neos only need to be 3 months old?

I can't think of anything else that is setting off warning signs so hopefully you will get shrimplets from the CRS soon, it will probably all happen in one go! You obviously know what you are doing and everything sounds right! Maybe it will just take a bit more patience, or someone else may know something that I have missed?

crystals have been known to breed at 5 weeks but i always sa 3 months i may just put some crystal in a smaller tank and see what happens if they start to breed stright away it will prove big tanks are not the best,

That sounds a  great plan and experiment. I would be most interested in the results, if you do decide to do that?

I don't doubt you will get them breeding in the big tank at some point, but maybe it does just take longer for the bigger tanks to establish and settle etc.

Oh, wow! That really is a surprise then!

Maybe your best bet will be to set up a breeder tank which you can then transfer them later into the bigger tank, I guess that will help with getting the best colours possible as well, selective breeding etc?

Clutching a bit at straws here, but, It may be worth doing a significant water change if that is an old tank and usually only has a small change. Fresh water usually seems to excite my shrimps and I have noticed this often happens, I guess it is the equivalent of rain falling in the wild and seems to encourage moulting and frantic swimming!

I would wait and see if anyone else  has any useful advice on here first though as it is quite likely someone has had your same experience and will know what to do but they may be in a different time zone etc so give it a day or so. 

That plan to set up a small tank though is a good one and worth a bash, especially if you already have an old one lying about anyway. I do have some links on my computer so will read those and see if that throws anything up and let you know if I come across anything, probably be tomorrow now though!

your idea of a small tank is worth a shot theres also black bee in the same tank that are not breeding they are the left overs from the transfer to a small tank

Do you have a TDS meter and know if the 2 tanks are the same, the older larger one may have crept up over the years?

ps Power outage here for a few hours today so I haven't ignored you if you don't hear for a while.

Both identical the smaller tank was sourced from the large one Shrimp,water,filter this is what I dont understand TDS meter used every day on all 11 tanks gh/kh ph tested weekly all filled with RO water reminerilisd with gh+

Power back on here, hopefully for good!

Logic dictates that if everything is the same as ALL the other tanks and they are breeding ok in those, it must be the only variable which would be the larger volume/capacity of the tank. If you have a spare small tank available then it would be worth trying that? At least then you will know for definite?

I did find this video and some of the 'comments' may be relevant/interesting?

https://www.youtube.com/watch?v=3s-aFNzwg3U

Maybe the larger tank needs to over-winter and it may help to try turning down the temperature slowly and see if that makes any difference to their behaviour. It must be a bit like plants in SoCal where my brother lived, roses don't work as they never get the winter break they need, and bulbs have to be dug up and put in the fridge to mimic winter? My tank temperature is 23, so same as yours and they have started breeding about a month ago after their winter break? Maybe a bigger tank takes longer to adjust do this!

      It sounds about right for GH6 (6 drops is roughly 120 TDS). Those GH test kits are not the most accurate. And RO water reading of 3 is not unreasonable. I don't know why you would have been reading 240TDS last week and now it's a 100 points lower. I would suggest, not changing water parameter with a water change for a week, then see where it is at. Change if it gets close to 200 (say around 180-190). Let's give the tank some stability by not changing anything for a while.

      I checked my TDS meter and it reads 3 on RO water and today my TDS in my tank is 133. I did a test with API and it took 6 drops so that's around 100 TDS.  I had 2 adolescents die overnight.  Should I only change water when it's over 200 TDS or should i continue with the 10% every week?  Thanks
    • supermansteve32
      I'll check it when I get off work tonight. I'll check my reader against pure RO water & tap, and do a GH test.  I'll also clean my TDS meter.  Thanks for your help everyone. 
    • beanbag
      If u have a GH test kit, then u can do a cross check, where each GH value in RO water made with SS equals about 20 ppm, e.g. GH 6 water will give you about 120 ppm.
    • sdlTBfanUK
      Are you sure the new reading is correct as that sounds unlikely, and I would have thought you would have had shrimps dying  with that sort of decrease. Do you have a second way of checking the TDS, or can you take a sample to a fish shop for them to test? I can't think of any reason that would happen or even heard of that before? Even if you had put pure RO water in last water change it wouldn't have dropped that far! If it is currently the TDS113 it will make adjusting easy as you just mix the water to the desired end TDS figure (140ish) and it will slowly go up to that. Simon
