Hi everyone Really could use some guidance here. I’ve put 25cherry shrimp and 10 blue velvets in my aquarium over the last month. I’m having a slow die off over that period, maybe 3 per week. I have absolutely no idea why, except MAYBE might be molting issues since I did once see a cherry shrimp with the “white ring of death”. I’m wondering if my water is just too hard for them. Unfortunately I like the knowhow to evaluate the carcasses to see if there was a molt issue involved there. Here are the parameters: Temperature: 73 pH: ~8 Kh/gh: both about 18 Nitrates/nitrites: 0 Nitrates: 20ppm Thank you!
