Are my loches happy

[nowey]

I recently purchased 6 clown loaches and 3 Burmese border loaches. They are in a 125 gal tank with good water flow. They eat like pigs and their color is real bright. Sometimes they go up and down one end of the glass for an hour non stop! Is there a problem or do they like doing this?
Thanks

Yes, they do that, they also like to swim up filters, play dead, jump out of the aquarium, climb the glass walls, and other owner-stress inducing antics.

mine also know that its me that they can get food from, so they pester me. they dont bother if i am at work in the evenings, they just loach about as normal when tom is about they are worse than dogs for looking pleading

I know it's a different species, but I have to tell you my kuhliis do that when I turn the tank lights off. I can see them by the light of the nightlight, just going up and down, up and down, up and down. I don't stay up all night to watch them, but it wouldn't surprise me if they continued till dawn.
