Is this normal for fish to act like this?

I don't know if I'm being to paranoid, but for some reason my two guppies just started to go crazy and they are swim rediculously fast up and down my tank glass and my gourami (the shy one) is now swim ridiculous fast back and forth against the glass and my platies just stay perfectly motionless at the very top of the tank and my neons have very big bellies. I am just paranoid or not.

 

our guppies go nuts up and down our tank too. I don't think its anything to worry about..?! Our gourami is generally calm, but once in a while he gets a burst of energy and swims back and forth like he's gotta be somewhere... I really have no idea, but I do know my fish do it too so maybe you'll be less paranoid..

 

how hot is the water?

 

Thanks Fish Addict, I was think ing the same thing and yeah, it turns out that my water was a bit too hot, now it is coller and the guppies and other fish seem more normal, thanks!
