95% crayfish fry gone

95% of crayfish fry had gone are as follows;-
• On 31/10/2015=40%, we suspected we didn’t add in the Chlorine, action immediately taken.

• On 1/11/2015=40%, we poured in too much water without a lot of place for them to breath, so we quickly reserved one side without the water

• Again, on 2/11/2015=10%, to try out, we took a risk by adding some salt in order to kill the bacteria.

• Again, on 6/11/2015=5%, after gap of few days, we suspected that not enough salt being added into the water.

• So, these is a latest photo which only 5 left over whereby initially 100 crayfish fries reduce to 5 crayfish fries at last!!
