my CRS shrimps keep dying

Recommended Posts

lebowskia

Hello  I have CRS shrimp tank and everyday 1 - 2 shrimp is dying I don't know why, my tds was high a bit but I'm getting lower tds slowy by change %15 every week now ( before add in tank put in water gh+ and make tds 140ppm) when I saw dead shrimp I think it's peace of shell on it, my tds is 260 ppm now, I will make it lower slowly. I did cycle my tank 2 week before add shrimps, I know it's very little, I didn't know. (sorry for my english btw)

my paremeters now:

tds: 260

temp: 24 degree

I don't know other paremeters but I'm going to buy ph meter, what else can I do? I'm trying everyting, I don't want to my shrimps die anymore, I have left 7 shrimps.

here is my shrimp photo after die:

Sorry to hear you only have 7 left. It may well end up they all die but at least then you can get everything sorted ready for a new batch. Be mentally preparing yorself for te fact that this batch probably will all die off but then you will have a chance to do it properly and don't feel too guilty as we all made mistakes at the start.

Your TDS is way too high still and you really need to get the GH, KH and PH test kits so that you can get more of an overall picture of the water. It may also be that the tank wasn't cycled?

When you change the water you should add the new water very slowly, usually the best method is to use a dripper of some kind! You can accelerate the rate of reducing the TDS by just using pure RO when you do the water change, but that could also prove too much for the shrimp if the new water is added too quickly and the shrimp may already be weakened from the time spent in the wrong water parameters.

Are  you still using RO filtered water using the filter that adds back minerals for drinking? I still think the zerowater jug would be your best bet as then you can still use the other RO water for drinking as well!

If TDS & pH are the only parameters we have, then keep reducing TDS to about 160.

I don't use anymore RO filtered water using the filter that adds back minerals, someone recomment me a spring water here that with right parameters, he said breeding with this water like years and I did waterchange 2 days ago with this water with gh+, my tds is 180 now, better than before I think? 2 shrimps died after waterchange, but now shrimps looks good, there is no death today, I'm really happy not dead any shrimp, I'm going to buy gh test this week, shrimps looks good and moving but there is peace of molt on head 2 shrimps, here is pics, but they are moving, its a big promblem? I hope they don't die,  Zerowater is expensive for me now, I think I will use this spring water for now untill use pure RO water.

Hopefully you are on the right road now and the spring water will work. The new water will usually make them molt. I can't see clearly enough the shell but they may just be eating it, which is normal.

Spring water usually has minerals in it so you will only find out if that is going to work by trial, I hope it works for you and the initial signs  are positive, so fingers crossed.

      Where are you based? As crabby says you will probably need to do some diy though you may find something you could use sold for Betta fish on ebay or amazon maybe? Anything that shares water may be more difficult to stop shrimps moving between sections any way they can find! Simon

      If you want to be using a single set of equipment, you'll need to go DIY. I would say make some sort of frame that fits snugly inside the tank, and run really fine netting over the frame, for the dividers? Or possibly just a big sheet of filter sponge that you can cut up. The latter has less water flow though.

      I am doing an experiment with my cherry shrimp on temperature dependant sex determination and I need a divided tank obviously the tank won’t need to be too big as I am just housing 1 male and 1 female in each section. ideally, I am looking for a rectangular tank divided into 3 sections so that I can breed 3 pairs at once. The sections will need to share water as I only want to use 1 set of equipment. But if they’re sharing water, I am concerned that after breeding, shrimplets will be able to move into each section through the holes which would ruin my experiment.  Does anybody know where I can get a divided tank suitable for my experiment that isn’t too costly or anything I could use as an alternative? Thanks

      I assume that they are reverting to wild type, though I've not had them looking quite like that, but I don't have blues, just the red. If they weren't from an established single type tank it can even happen with all shrimps that are one colour as the parents could be mixed or carrying mixed genes! You are probably best to remove the ones you don't like but if you are already at this stage it will probably happen more often and in larger numbers as tie goes on? As it is a mixed tank anyway, just removing the ones that are turning won't stop the problem as the reds and blues will cross breed anyway? Simon

      There are wild type neos, some red cherry and some dream blues in this tank.   I am starting to see some dark and glossy blackish brown shrimplets emerging in this tank.     Sent from my iPhone using Tapatalk Sent from my iPhone using Tapatalk
