Hey. I am starting up a 29gal with a wet-dry filter that was used previously in my saltwater tank. I want to get some input as to what kind of fish I can safely keep in a 29 and in what order I should add them, and a time frame for adding them as well. I like some of the cichlids I have seen at the fish store in town and I like the rainbow shark. Can I do a few cichlids and a rainbow shark? What's a good bottom feeder that will take care of some algae? Will that interfere with the rainbow shark? If you have pictures of the fish I'd love to see them. Thanks for all the help.
