All shrimp, dead :(

Just right now i went to my tank to do a little maintenance, i notice all the shrimp dead. Amanos, greens and cherrys. The fish seems fine just minding their own business. I tested water and all is normal as always, nothing different. But i did notice that my drop checker dropped and the liquid must have spilled out into the tank. Is the liquid in the drop checker poisonous? It could also be co2 poisining but cant tell since the drop checker is empty, but then again i havent touched the co2 in a long time.

Sad, sad day :(

That started happening to me last week. My shrimp were dropping dead one by one every day until most of the adults were gone. I tried putting carbon into the filter and doing water changes but the deaths just continued very slowly. The shrimp would be eating and looking fine and then dead the next day. Now only the babies and juvies remain :/ I sill don't know what happened.
There is no way that half of my shrimp (50+) died of old age in a week. It was 2 species too (tigers and blue pearls).
Yeah im about to do a water change. So is the drop checker liquid poisonous or could it be something else?

Im so bummed out, I might stop trying to raise shrimp for a while.
maybe all your adults were old and were just dying of old age, and they all happened to go at once?

I just got these like a month ago, most of them looked young so i doubt it was of old age.
I would assume that it is poisonous, but I am not 100% sure.
I asked if bromo blue was poisonous a while ago and everyone said it was fine. I asked because my dc dropped and emtied also and I was scared because I had some rarer plecos in there. But, that was in a larger tank and no fish. I would say in a smaller shrimp tank, chances are, the reagent would be a lot more harmful especially since shrimp are more sensitive.
At most there would be 3 drops of pH reagent in a drop checker. If the bromothymol blue reagent was that toxic it would come with warnings, and I don't think it does. There is some sodium hydroxide in the reagent too, I think, but a very small amount. The stuff is primarily water. I read the material safety data sheet for a typical pH bromothymol blue reagent - it is slightly toxic for people, but no data is available on animal toxicity. That's because the bromothymol blue dye is definitely toxic, but the reagent contains around .05% dye.
At the concentrations that we use bromothymol blue, it will not kill your shrimp. In addition, you really are only using a few drops, so it is a very small volume (i.e. say a hundred microlitres) of a 0.05 - 0.1% solution into your aquarium.
I think i used the ADA brand. Dont know if that makes a difference. Either way, my shrimp died and thats the only thing that was different in my tank.
I lost a lot of shrimp, though i lost them all but i saw a few of them acting normal. Atleast i didnt loose all of them.
Sorry about your shrimps dude. I had spilled some DC fluids before inside my tank but my shrimps were fine. It could be something else. Could be anything like food, water parameter , excess Co2 or anything that has been accidentally dropped inside. Aerating your tank right away should help if you still have some still alive.
i would check co2 and do a pretty big water change. just to be on the safe side i'd probably put the survivors in a container with an air stone.
What kind of water conditioner did you use?
I lost 150+ CRS/CBS over night in 29 gal. few years back.....its still a mystery for me! God knows!

I was going to reference the same thing. Good one.

If it wasnt the DC fluid, it might have been the Co2. Even though i havent touched it in a while, i did remove the koralia pump i had running that ran current towards the top.

I do not use any conditioner, i use pure RO.

Damn, thats just sad. Sorry to hear that.

Do you still keep shrimp right now?
Yes I do Mate! but only few common RCS, amanos shrimps ...that morning I almost cried...
:( Don't give up mate! Try and figure it out, maybe wait a month and then try again. Get back on that horse...
