Danios scared of dwarf gouramis??

[psargon]

i just added 2 dwarf gouramis to a 20g tank that has some zebra danios. ever since i did that, the danios are swimming near the top whereas they used to go all over the place...are they feeling threatened by the gouramis???

anyone know what's going on?

Zebra danios are usually mid to top level dwellers so that's normal behavior for them. The gouramis are much more mid-level (although they do come up to the surface). Think of it this way: If you had free run of a tank and then two much bigger, more aggresive fish entered your space I reckon you'd get out of their way too! Gourami's can be little bullies so keep your eye on them, particularly while they are establishing their own territories in the tank.

ok. so i shouldn't be worried too much if i don't see the gouramis bullying the little guys?

No bullying = shouldn't worry.

However, be aware that sometimes bullying is going on once the lights are out so you may not see it. To be honest though, your danios should be able to outrun the gourami with ease!
