A few months ago I got a cleaner shrimp. He lasted about a month and then dissapeared. Just one day he was gone without a trace.
Last month I decided to try a camel shrimp. He hid in the rocks for two days. I could see him but he wouldn't come out for anything as far as I could see. Then he dissapeared.
What is going on?

All I can think of is that one of your fish killed it.....that or it's very sneaky....

i think it's possible the camel could be hiding, but the cleaner was very sociable and I'm sure he's a goner. thanks for the input!

It could just be hiding in/under a rock. They are not very social shrimp.
