Green chromis racing back and forth

[Baylott224]

I got 2 chromis that supposed been together for about a year so one is just swimming back and forth front glass but when I feed they both eat ALOT then a few minutes after the foods gone there he goes back and forth theres nothing on him or and scratches he looks fine eats fine. But the other one does not do this he acts normally

It's been like this since the morning I introduced them yesterday

And it was not doing that in the small little holding tank they were in when I bought them

How big is the tank? Is there enough rock work in the tank? A short video will help folks see and understand.

 

[Gumbies R Us]

A video or pictures of the fish/tank would help out a lot!

If you just introduced the fish, I would not be too worried. Give him a chance to settle into the tank and then assess is my opinion.
