Not sure if this is the right thread but I've had my cleaner shrimp for about a year and is perfectly fine. Just noticed yesterday that he has been in the corner of the tank for the whole day. Doesn't really move even when i feed the tank and usually when I feed the fish he comes to the top and takes it from my hand. Tank is a 40 long with refugium with full spectrum LEDs. There is only a clown, goby, a royal gama and a few crabs and snails. he is the only shrimp in the tank. Corals are few sps
and many lps
. Tank is doing very well. Any input would be great thanks.
