As you can tell in my signature, I have a 29g cycling that will be done sometime hopefully in this century (I a little anxious, can you tell?) and have been doing a lot of research about the fish I want to keep. There will be cories, blue gourami, angelfish, and tetras. From what I've read, the angel and blue gourami like calm water but cories like a current. Will this be a problem? It's probably a dumb question but I just want to get everything done right.
