So the Alphas came in! all bodys in the bag were alive and well. there are around 18 - 20 and one looks like a Opae ula
I ordered 12 so shrimpmart.net has done me good! I put them in a bowl and added some tank water to the bowl for 15 mins.
I have moved the dark red opae ula in tank#01 into my community tank for a short period until my new tank (#04 with lava rock) has matured and will continue to try and breed out dark red shrimps there, and in tank#01 which is now empty, I have put the alphas and moved the rock into the corner to offer some hiding spots. I will buy some more rocks and add these later. I was more bothered about getting them in some nice mature warm tank water.
The SG in the bag which they came in was around 1.006 - 1.008. I just hope they make the next 48 hours in the new tank!
