RCS dead
I saw my red cherry shrimp is dead. I have 6 of them in there but can only locate 3, plus the dead one. I'm afraid the others are dying/dead.

What do you think went wrong?

My tank temp is colder (72 degrees) and contains 0 ammonia 0 nitrites and 0 nitrates (using the API master test kit). There was a small ammonia spike (below .25 ppm) recently when I added two new loaches.

The tank is a 37 gallon planted tank. I haven't fed the shrimp any special food. I assumed they would eat the leftover algae wafers or the live plants.

Can anyone think of why my shrimp died? It was rather expensive so I'm very upset.

no nitrates is weird but what are the other fish... they might have eaten them

Sorry for the Necro but I would bet that it is the plant fertilizer that is killing your shrimp.

I was loosing shrimp in mass and it seemed to always be around my plant feeding schedule so I moved my shrimp tank to a tank that I didn't fertilize. I later found out that copper is extremely toxic to aquatic shrimp and is in most fertilizers.

Has anyone found a shrimp safe fertilizer. Would love to fertilize my shrimp tank without kilingl off my colony... thanks.

While it could be the fertilizer I doubt it. Most have such small amounts of copper it's harmless to shrimp. I dose Seachems Comprehensive with shrimp in the tank with no problem. They also have root tabs too. Like Christople said they're probably being eaten. What fish are in with them? Also do they roam around a lot or stay hidden 90% of the time?

the loaches or a filter intake.

also the shrimp might not getting enough food

For shrimp keeping, try not to intro any fertilizer and also watch the ph. If ph swings too much, shrimps will die easily.

if you are using chelated copper you should be ok.

I used to dose premixed dry ferts and was fine.

The pH swings on the other hand are a no-no. Are you injecting CO2? That can cause water acidification if you are not careful.
