Hi,
I recently set up an aquarium with following details:
Mostly Sand and lot of pebbles.
4 well grown plants
One big submersible Filter
One Air pump

I used Bore well water and let it stand for over a week.

Today, i introduced a pair of Angel Fish in it and i saw them get into
a corner of the aquarium and never moved out of it. It doesn't make
any big movements and just keeps swimming only in the corner. After
about 3 hours of putting in the Angel fish, I also put a pair of Shark
fish and they seem to be moving well around the place.

Is this a normal behaviour of the Angel fish or is there anything wrong ?!

Regards,
SUnil
