So my yellow neos have stopped breeding for a month now and I just don't get it. I have 4 neo tanks with exactly the same parameters, feeding schedule, temp, and water change schedules and my yellows just stopped breeding for no apparent reason. The breeder that I got my shrimp from also said his stopped breeding and his parameters are similar to mine. My blue neos , cherries, and oranges are being berried left and right but it just seems really odd my yellows are the only ones not breeding. Any experience this? Ph 7. 5 0/0/5 tds 220 temp 70-73
