Amano shrimp turned up dead

My amano shrimp just turned up dead today. Starting a few days ago, its body starting turning a more opaque white color. Eventually, starting yesterday, the shrimp became lethargic; it would stay in only one spot and would not even eat. It was like that again this morning until it passed while I was at school. The cherry shrimp I have with it don't show any similar symptoms. My parameters are A/N/N: 0/0/0. My guess is that my water temperature was too high? It usually reaches up to and stays around 80F since it's summer right now. Can anyone else chime in with their ideas why?
I forgot to mention: I see a larger than normal amount of cherry shrimps hanging out around the top of the aquarium

 

What kind of filtration do you run? It sounds like it might be an oxygen deprivation issue, high temperatures deplete oxygen in the water faster and if your surface agitation isn't adequate it might cause a sudden drop, in which case it's common that the larger creatures feel the effect sooner.

 

I’d assume the cherry shrimp are more sensitive than the amanos, that’s been my personal experience.
80f is a little high for cherries and amanos but again amanos are more hardy. Do you run an air stone ?

What do you feed ? You could be seeing a moulting issue possibly.

another issue could be age .

I run the stock filter on this Imagitarium aquarium. And now that you mention it, it does not provide a lot of filtration. The filter compartment draws in water through the sponges and then shoots out the cleaned water through a little jet, but it barely creates ripples on the surface.

I do not run an airstone. I feed Hikari shrimp cuisine, sinking wafers, and algae wafers but with an emphasis on the former two. The shrimp seem to molt normally so i'm not sure if that is the issue. I got this amano shrimp about half a year ago.

 

You could try to add an air stone and see if that helps your remaining shrimp calm down. That they hang more at the surface than usual is what makes me think it could be an oxygen issue, especially in the summer when it gets hot, shrimp don't need a whole lot of filtration but they need oxygen the same as anything else alive. That's why so a many use sponge filters to provide both oxygenation and shrimp-safe filtration, but an air stone might solve your immediate problem.

Would an airstone be effective if I left it in this compartment? The wall seperates the filtering process from the rest of the tank. I just don't want the airstone to be noticeable elsewhere in the tank.

I'm not familiar with this type of tank, but probably as long as you get enough surface agitation and gas exchange, where it is in the system doesn't matter.

One more thing: do you have any recommendations for a quiet airstone?

I don't know about quiet, just a quiet pump. Some put the stone into the HOB outflow to send more O2 out and I've considered it. I have to dig an extra pump out when I remember. I think with your shrimp seemingly in distress, you need that airstone or extra sponge filter in there soon.

Yep. Right now I've been floating bags of frozen distilled water to drop the temperature a little bit but it's not that great of an option. I already got an old airstone and pump from my dad but I've gotta clean it first.
