Help! My Yamato shrimp dying!!!

Improper PH, KH, or GH. Too much Ammonia, Nitrite (NO2), Nitrate (NO3). Most likely reasons. Have your water tested. If you don't have a kit, borrow one, or take a sample to the LFS where you got your shrimp (they might test it for you).

Unfortunately I haven't found a local LFS that offers this service yet. I think the assumption is if you're serious enough to want to know your water parameters, you'll be willing to buy a set of test kits yourself.

Also 30C over prolonged periods is probably not healthy for your livestock, a fan should definitely get it below 28C, but you will have to be prepared to daily water topups due to evaporation.

i try to keep shrimp tanks free of ferts. it stresses them. and also 50% water change a week is quite upsetting to the shrimps. they get wonky if water chemistry changes too much too often.

Well, I am sure it would not hurt to ask... Maybe even offer a small fee to borrow the shopkeepers kit, and bring your water sample. Who would refuse that?
Man you crack me up. Who says above 28C is unhealthy for every species? If you supplement ample oxygen, than 30C is not a problem for Yamato shrimp. I guarantee it!

Yes, agreed! Try changing 50% or more a week, can cause casualties for sure. I think a major problem people overlook is the shrimp needs to molt after a major water change. If they molt more than 1x per week they can die! Some might molt then die, others may just die while attempting to molt. Probably very stressful for them.
