Strange things have been happening in my rasbora/shrimp tank. Yesterday I had my first shrimp death, and today I found 4 shrimp that have molted...I only have 15 shrimp. I've never caught the rasboras in the act, but sometimes I see them "hovering" towards the substrate looking around. Any ideas why 1 shrimp would die and then 4 would molt??? And Jim pretty sure it is the rasboras, but these particular shrimp i got 2 and a half months ago and the rasboras never bothered them back then, only eating the baby shrimp..
