Ok, I love shrimp and have a ton of them. Right now, I have a coral banded and 2 blood shrimp. My mated pair of skunks passed away a few months ago, I had them for a couple of years. All were living together in a 100 gallon, no problems at all. Each had its own area of operation, but I do have 150+ pounds of LR
in this tank.
Well, as far as behavior of shrimp, here is my 2 cents worth.
Coral banded - hide all day long, 10 seconds after you turn the lights out it will be all over the tank, you will see him every night.
Skunk cleaners - will always be within a spit second of hiding behind some rock, but will be out and about for the most part. They will even get used to your hand cleaning the inside of the tank and jump on it to pick skin off. Very good shrimp to keep - the best by far, for a bunch of reasons. You will see it, and it will (often) pick parasites off your fish. Not always though, they tend to prefer the food you put into the tank.
Perpermints and camel shrimp - when I kept these, they always just hid out in the rock and I never saw them, ever. I never even knew when they died.
Blood/fire shrimp. By far, the most awesome looking shrimp there is, but VERY shy. I have had two of these for almost a year now and I had to move them to my 24 gallon nano just to have a chance to see them every now and then. If they die, it will take a few days for you to find out more than likely.
Pistol - great nano shrimp. I say that because they can get 'lost' in a big tank with a lot of rock in it. You will never forget that SNAP in the middle of the night - don't put these in a room that you want to sleep in. VERY hardy shrimp, probably the toughest of the bunch. Also a night animal, if want to see him move arround, turn the lights out.
sexy shrimp - one of the coolest shrimp but so tiny most reef fish will eat him. I have a couple in with my fire shrimps in my 24 gallon nano. This shrimp is ALWAYS perched on some coral somewhere waving his butt in the air in plain view. If you have not seen this, go check it out. By far, the most 'not shy' shrimp I have ever kept, so long as you are not trying to net him, then he is gone.
Good luck with your shrimp
