Help - mysterious death

Recommended Posts


Hi guys,

Please help! I'm encountering some CRS death over few weeks in one of my tanks. I just scoop one this morning (photo 2) and it was very pale.

Tank uses benibachi soil and RO. Put AIL and alder cones.

pH:6.3; Temp: 23C; gH:7; kH: 0, ammonia: 0; nitrite: 15ppm, TDS:125

I feed glasgarten bacter AE, glasgarten immunoglutan, shrimpydaddy's sinewy, shirakura and benibachi baby food

Symptom I observed that they show translucent body (photo 1, the middle one) - is this a disease or malnutrition?

Occasionally I blanch some green vegie to them - could pesticide kill them even after thorough clean and blanch?

Thing that puzzle me I have another tank (I keep carbon rili mix with CRS) that have same configuration as the tank where I get dead CRS but have no casualty over months.

Please some input and advice

Nitrite 15ppm ?

Is this Nitrite or Nitrate?


If it's nitrite, then that's your problem.

It's nitrate Jayc.

Do you think Purigen would be a suspect too?

i have almost zero experience with bee shrimp but it looks more likely to be a bacterial infection. im 99% sure it is not malnutrition.

Mine went translucent when they were stressed.

      One of my blue bolt youngsters has gotten this odd parasite or something attached to its shell.
      The shrimp itself is very lethargic and I don't expect it to survive, so I've isolated it from the tank.
      However, I'm baffled about what this may be. I've tried 3 salt baths without any result and now I'm trying a mix of Esha Exit and 2000 just to see if it will make the damn thing fall off the shrimp.
      Does anyone here has some good guesses or knows what it is?

      It may be a good idea to 'at least' decide Bee shrimp or Cherry shrimp at this stage, as they prefer different water parameters and you can then work towards those ideals? As blue ridge has said, Flip import most of their shrimp from what I have seen on the youtube videos? Simon

      Have you actually seen one of these? I got one and it had great pictures but it isn't really about anything in particular and I binned the one I got as apart from the great photos there was nothing really of interest just bits and pieces about 'breeders n keepers', so I couldn't complain as that was what it was called. I wanted a book about all aspects of keeping shrimps and this wasn't that. I believe one f the experts has written a book and I wish I bought it when I saw it on my suppliers website as it has also gone now. I recommend seeing one before buying though as it MAY not be what you want/think it is???? Simon

      Gotcha. I’ve really been eyeing some ,”Fire Reds,” or some,”Blue Dreams,” from LRBretz, those are out of this world.

      Does anyone know if these are in print anywhere? They don't seem to print nearly enough copies to meet demand, issue after issue sells out and is gone forever.

      I wonder why that would be? I'd think an oak is an oak wherever it's growing. Perhaps a result of me leaving them in the sun? It's not a big issue, once they get soaked they become pliable and soft it's just a head scratcher...
