I have one 3+ year old shrimp and 8 others that are homing in on being with me for 2 years now. When researhing them, I kept reading that
they are nocturnal. Somewhere, I did read once that they were active during the day, so I decided to go ahead and give it a try. Mine are active 24/7. Bc there are so few, it is easy to keep track of them.
And just when I think I have caught one napping--nope--he's picking at the substrate again. I'm beginning to wonder if they sleep in cat naps. I am keeping them in a container in natural light in front of a sheer curtain in an east window where they get about 3 hours of filtered sun a day. The rest is boring regular light. Could that have anything to do with it? I originally saw a guy in HI on youtube who did the same (no filtering curtain) and it worked great for them. Is it the natural light? Anyone who keeps them with aquarium bulbs--are yours 24/7 too? I love being to see them moving around all the time.

Also, I originally read they hide a lot and mine don't. They prefer to be on top of the lava rock or on the walls. Often all at the same time. Which is great for me. They hate spirulina. They like to slip out of their shells by hanging from something. When I had black twig coral, it was on that. Now with a bit of spiraling java moss, it is that. I assume gravity helps them slip out--someting I've been lucky enough to see a couple of times.

Anyone else having HRS acting differently than advertised? Would love to here about it. Also, my guys don''t spook easily. Much better than fishes but not as good as snails. They HATE aeration. That is the only thing that freaks them out.

Maybe they haven't yet had a chance to read the current publications?

Bow chicka bow bow! Man has a point.

They never seem to pick up or read their newspapers. It makes sense to me.

I wonder how they manage to poop so often without any reading material?

My red shrimp are much more active at night and they like to hide. By active at night I don't mean that they sleep during the day, since arthropods don't sleep, but they don't move about as much even within their hiding places. Mine happily eat spirulina but won't feed at the surface at all (which is a learned behavior anyway.) They're in a 10g lit with CFLs and the tank contains an air powered sponge filter.

Mine hide all the time. Occasionally Ill see maybe 2-3 on the front of the glass picking at the algae. Most of the time they hide between the lava rocks.

maybe the lighting? maybe depth of lava rock?

Jason--you were breeding them a while back weren't you? Would you describe your lighting as low, medium, or high?

I also wonder if the depth of the lava rocks matter. Mine goes from one inch or so on up only to about three so there is less places for them to wander around looking for food, etc. in there so maybe they may as well stay on top while I could see if someone piled lava rocks practically to the water line on one side, they would spend a lot of time in there exploring and wouldn't be out in the open as much then.

And mine could very well be most active in general at night too, but they are definitely moving around all the time during the day.

I just think the differences are interesting.
