My pH for my green shrimps and snowball shrimps are around 7.8 to 8.2.
The water temperature for this tank is around 82 - 86 F (27 - 30 C) in the summer time, and they seem to breed pretty well still (snowball shrimp wise since my green shrimps were in the juvenile stage during this summer). And in the fall (just recently) to spring, the temperature ranges from 72 - 79 F (22 - 26 C), and they are still breeding. Basically these shrimps (green and snowball shrimps) are very temperature tolerant. However, the pH is the main factor for the Green shrimps. They like it above pH of 7.0 and like hard water parameters. I hope this helps. Very Happy
Oh just a side note: most of my juveniles finally grew to the early stages of adulthood recently (FINALLY!) Rolling Eyes . There are some females already developing their green ovaries already. In fact, one of them is carrying some eggs (just checked this morning). I guess since they are still young adults (small in size), they do not carry as much eggs as the old adult females I used to have Confused . However, I still have 1 old female adult in there and she also is developing her ovaries as well. I will let you guys know how many eggs she will be carrying when her time comes.
Wow, sounds like they really do grow really slowly!
They look so cool though
Thanks for posting the info too.
