Adult yamato shrimp dying after a few days!?

[jackwolf]

My planted 2 footer contains small fishes such as sparkling gourami, darios, enders, some small unknown species for about two months and so far all fishes are okay. However I have problem adding in yamatos which I needed to get rid of the hair algae that grow on some of the plant. Each time I add in adult yamatos, I could find them dying one by one each day. I thought yamato should be the most hardy shrimp around.

What could be the possible cause of this failure...? I thought my water condition should be rather fine since the small fishes has no problem...

Things that I add in to the tank:
Ocean Nutrition Giovanni's plant nutrition Iron+, Trace+ & Fertil+, accordingly to the instruction of 1ml per 10L per week.
Nothing else. I have DIY CO2.

i find malayans and cherries more hardy than yamatos so they aren't the most hardy shrimp around

did you acclimitize the shrimp properly?

before adding the yamato there's cherry & orange shrimps already in the tank for quite some time.. so I thought the water condition should be okay.. yamato die, but not the cherry and orange... I need yamato to clean-up the hair algae..

Sudden change in water condition can kill them. That is why we need to acclimatize them before introducing to new environment.

I had the same problem as you. Do you have a fan? After I added a fan, my yamatos stopped dying. Maybe you could try a fan.
