Hi...
Emperor is ok...but its hard to come by...not easy to find them.
As for the M'sian blue, i dunno wat it is...got a pix ?
I doubt that it is the Heterometrus cyaneus...those are super rare.

Ithink the common spinifer are good enough.
The petshop at Summit subang got some big ones though...but u must ask for a good price...Good luck 
Just back from Husin's corner...and donated a baby. to him. A babycurus tat is...
All my stocks will be there for today...will take them back and organize and rehouse them. Any spares will be on display at Husin's corner...If u guys wanna see, its still there until i collect them later on. One reminder though, u need to open ur eyes bigger coz they are small...and tiny. especially the gracilis and the dentatus...basically still 3rd instar...but they are gorgeous...especially my babys
