Daneland Posted February 13, 2016 Report Share Posted February 13, 2016 Hello guys I am afraid I have a major problem.My shrimps are dying.Today I pulled 4 of them from the tank,this week probably more than 10. All water parameters are fine 0 ammonia,0 nitrite,5 nitrate.212 TDS,6.4 pH.Besides there are rili shrimps they are not sensitive shrimps to water parameters. They become very inactive ,sluggish and disappear until I look for them and pulled from the tank. I notice they become a few of them had become kinda frosty looking before they died ; not all of them though. There has been some problems with breeding but recently I saw one (and only) berried shrimp form rilis.But there were no dead shrimps on the floor. I guess it has been going on for now I think but has become much faster. I have not added any plant for a very long time ,we dont use any pesticides ,hair spray etc at home. I think it could be a slow poisoning or infection. The interesting detail there are some tiger shrimps I have not noticed a dead tiger and their numbers are stable (I guess ) I will use tetracycline for infection and if it doesnot help I guess I will remove everything from the tank will change substrate ( pond soil and cat litter) Any ideas Quote Link to comment Share on other sites More sharing options...
Soothing Shrimp Posted February 13, 2016 Report Share Posted February 13, 2016 How long as your tank been set up before adding shrimp? How did you acclimate your shrimp, and how long have you had them? What is your gh? Tap or ro? Daneland 1 Quote Link to comment Share on other sites More sharing options...
monty703 Posted February 13, 2016 Report Share Posted February 13, 2016 I would say the PH is too low for neos! Tigers can adapt but the neos may not like the PH at 6.4 Daneland 1 Quote Link to comment Share on other sites More sharing options...
Daneland Posted February 13, 2016 Author Report Share Posted February 13, 2016 It has been a year or more since first set up and shrimp are my breds ,they were born in to the tank ( added tigers 3-4 months ago may be more) Tap rainwater mix.Rainwater comes from gutter ,I will stop using them. gh is 5 (too low !?!?) I thought about pH and checked the internet it says it should be all right ?! Too confused Quote Link to comment Share on other sites More sharing options...
monty703 Posted February 13, 2016 Report Share Posted February 13, 2016 If your using rainwater, is it possible something has contaminated that water? What about Copper. Shrimps are highly susceptible to copper. I never kept my neos in water below PH 7. Shrimp Life 1 Quote Link to comment Share on other sites More sharing options...
Shrimp Life Posted February 13, 2016 Report Share Posted February 13, 2016 I agree if they are dropping dead could it be copper or some other poison/contaminant Quote Link to comment Share on other sites More sharing options...
Vpier Posted February 13, 2016 Report Share Posted February 13, 2016 Do you have a copper test? Poly-Filter is also a good way to test for metals because of its ability to change color depending on what metals are in the water and will pull out contaminants like purigen. Where are you from? You could have some type of acid rain that contained pollutants? Quote Link to comment Share on other sites More sharing options...

Daneland Posted February 13, 2016 Author Report Share Posted February 13, 2016 I guess it is rainwater.I will do %80 WC with RO + tap mix (same TDS) over a few hours slowly. And another 50% maybe in 3-4 days. Thanks for you replies Quote Link to comment Share on other sites More sharing options...
Lyana Posted February 14, 2016 Report Share Posted February 14, 2016 Did they start dying after you got tigers? Turnig frosty could be some kind of infection. Anything change before they started dying? Quote Link to comment Share on other sites More sharing options...
Daneland Posted February 14, 2016 Author Report Share Posted February 14, 2016 I changed the water from 100% tap to rainwater/tap mix but it was 2-3 months ago.I added tigers around same time.I will get some doxycycline as but dont know how to keep filters safe.Maybe I should remove and leave in a bucket for a few days.I dont know...

Thanks for you replies How much % WC??? 80% then 50%? Be careful! Don't do more than 25% at a time a let it recover a bit before doing another or you may notice a slow decline in tank health until it becomes microbially reestablished. The white on the shell may indicate a molting death, but your params look alright so it does sound more like a heavy metals problem. You could purchase a chelation agent to remove them. However, I'd recommend 10% WCs every 2-3 days for a week or two using RO/DI water, making sure to remineralize it to 4-8 GH (which is where you're about at) and around 80-200 ppm TDS. Also you're gonna wanna raise the pH from 6.4 a few points and likely the alkalinity (did you test the KH?). I'd recommend starting with a target of 6.8 and try to get there over a few days using pinches at a time of a shrimp safe buffer, like SeaChem's alkaline buffer or even pure baking soda from the market. You can also get salty shrimps GH+/KH+, who anyone will recommend for raising alkalinity and hardness/TDS. Then repeat, but no more than 0.1-0.2 pH jumps each day or two. I keep my rilis around 7.0-7.4, depending on the tank, and they all do quite well. Good luck. I hope you see good results in your tanks in the upcoming weeks.

35ppt Posted February 14, 2016 Report Share Posted February 14, 2016 Bearing in mind there may not be one single cause. The rainwater could be an issue, and/or pH. And I am wondering about it being molt issues. I think they do/can turn white looking before a molt, and sometimes they fail. The inactivity also seems to be consistent with a molt issue. I think? kitty litter removes carbonates from the water. What are you using to remineralize? Mr. F 1 Quote Link to comment Share on other sites More sharing options...

I think? kitty litter removes carbonates from the water. What are you using to remineralize? Tap water .It is rock hard.I check TDS to keep it level.I check mix (RW/Tap) for KH and GH than add this water to the tank.I have stopped RW all together, I will stop tap water soon. RO+shrimp mineral. I think it will be a bit an overkill for rilis but i will be able to control most parameters if not all Quote Link to comment Share on other sites More sharing options...

Soothing Shrimp Posted February 14, 2016 Report Share Posted February 14, 2016 Daneland, if it's any help- when I first started neos I used tap too. I couldn't figure out why I was losing shrimp. Then I did ro + remin and miraculously they were surviving. Some people have perfect water from the tap. Although my params read fine, I did not. One of the many things I learned along the way.

Lyana Posted February 16, 2016 Report Share Posted February 16, 2016 I also had a hard time with my shrimp until I switched over to ro water. They wouldn't hold eggs and had no color. Soothing Shrimp 1 Quote Link to comment Share on other sites More sharing options...

Daneland Posted February 18, 2016 Author Report Share Posted February 18, 2016 I moved them in a new tank with old filters but they still keep dying. It has become a shrimp cemetery It is a completely hopeless situation.I noticed some of them get a blueish hue before they die. I guess it is a kind of poisoning and rookie mistakes combination. The only good thing there was a berried black nice tiger shrimp. I took the risk and transferred in to relatively high grade shrimp tank.Now I have some shrimplets Edit in the cemetery tank I have seen a berried rili today .I cant get my head around it?
