Tiger Barbs

[DKlar42]

I have 6 Tiger Barbs and the 3 biggest and oldest are, out of nowhere, beginning to hover head down towards the sand in the right corner of the fish tank. All of them are completely fine, the other 3 go on with schooling. the 3 juveniles will come back and then they will all school. They all eat well and the 3 that hover get spooked when I get ANYWHERE near the tank and when I move away, back to position. Nothings wrong with them and everything in the tank is fine. Just wondering if anyone knew why this is?

I Have 11 Tiger Barbs, mine all do the same thing, I find when I switch the tank light off for the evening they do this. I think that is how they sleep or rest.

Fish will sleep in the daytime(lights on).
