I have a 30G (might be 27-29G) with five Albino Cory Catfish, and would like to explore my options as far as stocking goes. I would ideally like to have a large, vibrant fish with somewhat of a personality, and if possible school of smaller fish other than bottom dwellers. Also, I would like to explore the possibility of adding more Cories. I have read a tad bit about Cichlids and from what I have heard they are rather large and vibrant and have unique personalities. Other than that I don't know anything about them. The fish need to be rather hardy as even though I've had the tank for several years now, I don't have a lot of time to dedicate to the maintence and feeding.
