shrimp swimming at the surface

so just last night i changed the filter on my 5.5 gal shrimp tank to a zoomed 501 with the spray bar. There are both cherry and CRS shrimp in there all the cherry are juvi and CRS mostly adult with about 5 juvie. anyways when i woke up, all the cherry shrimp were swimming up at the surface like they were drunk. they were spinning and twirling around. i thought there might not be enough air for them or something so i raised the spray bar so the streams would break the surface, but the thing that was odd was that it was only the cherry shrimps doing this. any ideas? also the spray bar seems to have a lot more flow what should i do to reduce this?

Did you completely replace the filters as in take the old one off and the new one in? If so, you took off a majority of your beneficial bacteria that convert ammonia>nitrite>nitrate. You may be going through a cycle now if you took the old filter off.

Do you know if they were male or female shrimp or both? Males tend to get a lil swim crazy when a female is ready for some lovin. Mine go all over the tank looking for the lucky lass.

You shouldn't take life to seriously. You'll never get out alive.

To reduce spray bar flow you can take a drill and drill more holes in the spray bar, or enlarge the holes that are already there.

At the risk of sounding crazy, I noticed my shrimp went crazy right before an earthquake. Last night my RCS were all over the tank and just this evening I read a 5.7 magnitude shaker hit up north.
