Hi all

I have the following variables:
4ft Tank
Planted with lots of moss

Bio Load

28 Yamato Shrimps
30 Cherry Shrimps
2 Bee Shrimp
1 Tiger Shrimp
3 Otos
2 SAEs



Water Parameters

Kh:8.5
pH:7.2
Co2: 16ppm

QUESTION:

1) My bees and tigers started to decline from an initial population of 100 (each) to 2 and 1 respectively.

As such, is there anything wrong with my variables as described above. My Cherry & Yamatos (which were either multiplying or growing) and they seemed very healthy.

Pls advise as what has gone wrong with my setup. Thanks

You have Cherries and Yamatos breeding in the same tank?

Yup,

Cherries are populating like wild rabbits but for the yamatos, they seems to be getting pregnant very often but there are no fries in sight.

Do you have anything in the tank that might be rotting? Any driftwood? Bees and Tigers are more sensitive animals (in general) than Cherry Reds and C. japonica. Hence, they might also be sensitive to the CO2, although I cannot confirm that since I do not use CO2 in my bee or tiger shrimp tanks (or any tanks for that matter).

Okay, that makes sense. Yamato larvae can not survive in freshwater.

Yup there are two pcs of drift wood that is tied with Moss (Java, Xmas Errect Moss).

The surviving shrimps seem to be very happy and growing. So i am really stunned by the sudden departure of them.

Anyone has similar problems?
