hey, welcome to mfk..! am thinking ya still have a little too much gravel in there, but it is definitely better than the first photos ya posted. with all the fish ya have in there now, you are about "topped out" in relation to the amount of filtration, space and what not... a 20 gal is ok to "grow out" a couple angels by the way, but is not suitable for them for longterm... take care and good luck with yer fishies!!
