I am currently in the process of fishless cycling my new 50g. I'm running a penguin bio-wheel 350. When the time comes to add my fish I am really leaning towards a few angels. My problem is I have been getting conflicting opinions on how many angels I should add. I had originally planned on only 2 but there have been people telling me 4 or 5? This seems like too many. Also what others will do well with angels? Thanks for any input!!!
