Aquarium Ecology

Hello,

I have what I believe to be Amano Shrimp. A female was gravid and the eggs hatched a day ago. I left the zoes in the hatching tank for a day with light airation and heater while I prepared a full salinity 33/34 ppm growing tank for the zoes. Until this morning many zoes died as I believe (maybe I m wrong) and I have now transfered the remaining zoes into the saltwater tank. Unfortunately I cannot see any of them gliding in the tank since the water is green. The really interesting thing is that the when I placed the female shrimp into her original tank which is shrimp only and planted, she kept some eggs which hatched into the main tank. Now I see zoes not gliding in the water BUT stuck on the glass moving about the tank using the tank's side glasses!!!! How can it be that in the main tank the zoes are stuck on the glass moving about and in the hatching tank the zoes were hanging upside down gliding in the water?????!!!!

Thanks
