The current in my 55 gallon is pretty strong and I'm looking for suggestions on fish that will not have a problem with the current. The 5 danios in there seems to love it but I'm looking to add a bit more variety to the tank and don't want to just get more danios. Any suggestions?
You could try searching http://www.fishprofiles.com/profiles/#finder by selecting "stream", or type in the name of your fish and click on the "compatible species" link. Once you see any fish that interest you, I'd verify the info somewhere else jic. Sometimes compatiblity charts aren't "perfect"...
