I had bought five shrimp just a day ago. Later last night I only counted two. Today I can't see any. I siphoned the gravel, nothing. Then I picked up some decorations and found one dead body. I think they might've all died but I can't find more bodies and I don't want to cause an ammonia spike by not being able to find and remove them. I wanted to see if the shrimp would be compatible with my other fish (mollies and platies). Is it possible my fish ate them? My tank is established, unfortunately I can't tell you parameters because I don't have a test kit. I don't know why else they would've died, maybe just an unlucky purchase?
