Unhappy High PH and RCS

I recently started a solely shrimp tank in a 5gal tank that's been running for a little over a month and a half seeded from one of my other planted tanks. After adding the RCS after there were no visible ammonia, nitrites, or nitrates. I did a drip acclimation and introduced them to their new homes after finishing their acclimation. They were active the first day, the next day they settled in with a few molting. The third and fourth day they were actively foraging the fauna and interacting with each other. Around the ninth and tenth day that's when they began dropping like flies .
My stats are below, but i'm wondering if i did something wrong for them to drop like flies. Is it because my pH is so high or is it because I didn't receive them earlier, i was supposed to get them within two to three days but got them in five days . They were fine as far as i could tell (was shipped in a Kordon breather bag along with some

My substrate is 10 lbs of Ecocomplete

SŁŖwassertang, Bacopa monnieri (Money wort), narrow leaf java fern, and three broad leaf amazon swords.
(Did not fertilize during cycle nor did i fertilize after received the shrimps, only after their deaths)

Fauna: formerly eleven red cherry shrimps added after a month and half's cycle ( ten juveniles and one shrimplet) now one female crown tail betta

My water conditions are:
water is tap
8.0 pH
0ppm Ammonia
0ppm Nitrite
0 ppm Nitrate
(tested before shrimps where added, and after no visible fluctuations, test kit is API's liquid test kit)

Temperature is kept at 74 degrees Fahrenheit.

So my question what I did wrong, was it the pH at 8.0 or was it perhaps they were already in trouble due to the fact that they were held in transit for so long. Anyways I'm not going to let this stop me at raising rcs, but I would like some guidance as to better myself at keeping shrimps. I've had great luck with fishes but so far none with shrimps.

Everything seems alright to me. Your pH is on the high end of the RCS tolerance but they *should* be able to handle anything from 6.3 to 8.0. RCS generally will not die due to transit unless they were sitting outside in super hot/cold weather without a cold/heat pack.

I dunno, I've kept them in pH=8.5 with no problems, they bred successfully and everything. Wish I could help, but that's about it.

i thought as much, but there's nothing that i can think of that could have caused them to drop so fast, unless there's copper present in my waters, I'll probably have to test for that, but i doubt it as I own five ghost shrimp (one of which is berried) in my other tanks, and all water comes from the same source.

I've got a friend who's a fairly new shrimp keeper, and I gave him about 20 RCS this summer. His pH is about 8.4 and he's got dozens of shrimp now.

The tap water where I live is sky high hard and has a ph of 7.8-8.4 depending on whatever's going on at the water treatment plant that week and my RCS are breeding as fast as my pest ramshorns. I have some black tiger shrimp in there too that are surviving and look healthy, not breeding but I can't expect too much eh :p

My tap water is 8.9 straight from the faucet. 8.5 after treating with prime. My 10gal with Eco-complete, heater, airstone, and java moss is infested with Rcs.

My display tank with aqua soil has ph 7.7, but goes all the way down to 6.2 when c02 is on. No problems with the deep red adult Rcs in there. I've seen one shrimplet already, so there might be more hiding

If you decide to get more, I'd go with the plop and drop rather than drip acclimating them. Just pour the entire contents of the bag through a fish net, then dump them in the tank. I doubt that the deaths had anything to do with acclimating them as you did, but it's a lot faster and a number of people on here use that method with great results, especially with animals that have been shipped. The idea is basically to get them out of the foul stew they're sitting in ASAP, especially while they're stressed due to handling.

If you're still interested, I'd give them another try. They're generally amazingly hardy critters.

jasonpatterson okay thanks, will try the plop and drop with them next time, just ordered some more shrimps and they should be here soon (about twenty plus a few in case of DOA). Didn't know why I didn't try that before, I did that with my ottos and they are thriving, of course I have always had better luck with fishes than invertebrates. Will have to move my betta to the sorority, hopefully she is nice to the others.

Never mind, i do have luck with ghost shrimp lol bought five and still have five, one of which is berried, and all are starting to show some colored dots of green, brown, and red.
