With the weather warming up, I have increased the temperature of the shrimp rack to 24°C.  I also performed a small water change using straight RO water. This dropped the TDS by a few points and prompted the shrimp to moult and start breeding by simulating the rains which would occur during the wet season when food would be more abundant.

This shrimp was sitting in the bubbles caused by the spray bar and was in the perfect position to be able to see the eggs being carried under the carapace.

As can be seen from this image, the crystal shrimp have smaller eggs and carry more than the blue bolts.
