i have a 10 gal divided that I just put together... when one of my guys was in a smaller tank he had a bubbler in there and loved to watch/chase the bubbles. is it ok to add one to his side of the tank? if so, are there any cheap ones out there (i.e. under $10) that you would recommend? and is it possible to control the pressure?
also, my new guys seems to be hanging out at the top of the water a lot... any ideas why??
p.s. his old bubbler was part of the filter so i can't use that in the new setup...
