While I'm going thru cycling my 55G tank I thought I'd ask about fish. I have 2 small angels, 5 neons, 2 albino cory cats. I've heard the angels will grow big enough and eat the neons eventually, so I can leave them (neons) in the small tank with the corys. My better half wants a Gourami (sp). I would like another angel, other than that I want compatible colorful fish. I've been told I should have a bottom feeder and an algae eater. Whats the proper Ph for a community tank? 6.5-7.0?
