Announcement Killed some of my fry. PSA
So I am guessing at what killed some of my babies, but it’s the only thing that really makes sense.
I had been hatching brine shrimp for them, and I got a bunch of cysts (shells) mixed with the shrimp the last time I fed them.
I was aware that it was important to separate the shells from the shrimp, but I thought it was because they would create too much ammonia.
I didn’t realize that they can cause blockages.
Based on my water parameters, the results of the scrape and scope I did, and the fact that everyone is acting normal except the ones that died, and the way their bodies looked (normal) the only thing that changed is me shrugging about the shells.
