both will be too big, and the silver dollars to active, its not tall enough for angels55 gall
48x15x18
which are more placid with small fish?
will either teh spotted dollars or angels eat neon tetras??
mark...if the substrate is 2 inches and the water line an inch or so from the top its 15", what is the height from the top of the substrate to the water line?tank size is fine for angels only issue could be the neons. people have had neons with angels by getting the angels small and letting them grow up with the neons then they have much lesss risk of becoming lunch
