ok so im tryin to decide between a dwarf cichlid tank and a discus tank.i really enjoy discus but am a lil worried i can only fit a few in there...the dwarfs i have no real pref on but love the colors, and know i can get a bit more dwarfs.its a 55 planted tank with an xp2 and plant substrate black.anyone have any good ideas for unique 55, and also maybe a few pros and cons on the discus vs dwarf debate...and how many of each do you think i could fit in the 55...
