Yamatos and SAE all dead

[Phillipians]

Something's happening to my tank.
All 8 yamatos and 2 SAEs are dead. Fire shrimps look fine and my otos and galaxies are also ok. As of now, no more yamatos in the tank.

Any reasons for this? They look like paralysed or something and not able to move properly. Then suddenly all dead....

Any advice?

Maybe you can provide more information regarding your tank, in addition, was there any change you did recently?

[cheetf]

Did you pull out any plants?

Are the yamatos and sae new from Lfs?

[Shadow]

bro, need info on your tank, tank size, soil, filtration, cycle or not, ph, kh, etc. The more detail the better. SAE die where as fire shrimps OK is kind of weird, unless it was not healthy in the first place. New fish? Did you feed your fish?

[Phillipians]

Lots of algae for the sae to consume. Yamatos and sae bought from same Lfs 4 days back
Died 3 days after introduced to tank. Was healthy. And the new yamatos affected my old ones too so all yamatos died

1.5ft cube tank heavily planted. Will check my parameters in a short while...

[Phillipians]

Checked;
Nitrite and ammonia 0
Nitrate 5ppm
Gh3
Kh2
Ph 6
Recently did trimming and water change. No disturbance of the Ada soil at all. But the yamatos and sae cleared most of my dreaded hair algae or string algae... Think it's more like string, after they cleared it.. Die one by one. Poisonous algae?

Just curious if you did a drip acclimatization and quarantine routine with the new shrimps and fishes? 'cos if the LFS water parameters are different enough from yours, sometimes the shrimps and fishes could get pH shock and although they look okay, their resistance become low and end up dying one by one over a few days.

Or perhaps it could be a yamato shrimp specific disease somehow hitchhike on the new shrimps? Since even your existing yamato shrimps also died, yet the fire red shrimps still okay.

This is indeed quite a strange phenomenon.

i bought 4 yamato, all died in a week, crs surviving

i believe is ph issue

[Phillipians]

Hmmm, sounds like a possibility. But my current yamatos only died after the intro of the new crop... But PH sounds like a possibility.

Did you spray something near to your tank just before that, e.g. Shelltox? I killed my yamatos by doing that once while trying to kill a cockroach.
