I’m not entirely sure what’s going on with these guys. I ordered 3 and got 4. I thought they acclimated fine as they were drip acclimated over a 2 hour period along with Amano shrimp. Two died 4 days in after they were bulldozing around the tank eating algae and biofilm. Another one just died 11 days in. Hopefully the last one hangs in there. My tank parameters are all healthy 0 ammonia and 0 nitrites, 10ppm nitrates, GH and KH are in a range feasible for nerites. Temperature ranges between 77-79. I have 6 Amano shrimp thriving along with 10 leopard endlers, and 12 Pygmy corys I bought and stocked the tank the same day. I’m wondering if maybe they were compromised already during shipping and never really recovered well? From my understanding most of them are wild caught anyway, not sure if that’s the case here at flip aquatics, but it’s a bummer they are all dying ☹️ five stars for everyone else though!
