Your indo blue will turn into grey or brown cray later on. This is due to the farm injected the color or feeding with the hormon pellet. I kept 2 of them before.

I had 2 Australia blue crays. The pair bot from AI...RM100 each. The female was fight with another small normal brown cray. (was kept in 6 footer tank.) But then...she lost n died. damn damn..

The male...losing somewhere inside my 4ft planted tank. I had pairs of zebra, pink, black..etc cray. they will escape n climb out out the tank at nite. To prevent they escape. try to locate a plate of water somewhere near the tank. Then you will find them resting inside the plate on next morning.

If yr toilet/bath room nearby...then you will find them inside there.
