Hello, I have a betta in a one gallon fish bowl with an under gravel filtration system. He is extremely active, and swims about the bowl throughout the day, but lately I noticed a strange behavior where he rubs against the rocks, and/or his plastic plant and then lays down motionless...about ten minutes later, he's up and swimming again. --Could this be a sign of stress or illness? The "bowl" is actually triangular in shape, and I think the sides are reflective, so my first thought is that he might be afraid of the imaginary fish following him around constantly.
Is laying down typicall of betas, or do you think he's sick?
I'd appreciate any advice or insight into this!
Thanks!

Get a 10 gallon tank and put all together. 
Anyway, I want to keep the water clean, but I'm worried about stressing the fish out. Would scooping the fish out once a week be a problem? Or do you think I should focus on parshal changings?
