weird behavior...

[nono]

Hi , I've been wondering for so long because of my fish behaviour.My asian aro and florida gar like to rest at the bottom of my tank and seldomly swim near the surface , except at feeding time . I thought they are suppose to be a surface dweller ? I thought they are sick at first , but they have been in my tank for almost half a year and they still do the same kind of behaviour . Are those kind of behaviour are commonly happen ?thanks

Try adding power heads and bubblers. Sounds like a lack of oxygen to me.

You don 't any current blowing towards the place they like to stay near the bottom? No pump driving current their way in that place? Is it allways the same place, by the way?

No,they rarely rest at the bottom in the same spot.but recently,my aro seldomly rest at the bottom,but still doing it sometimes.my gar always at the bottom except at feeding time and at night.i don't have any device that make current
