Freshwater Aquarium/adding a dwarf gourami to a 5 gal tank with 5 other community fish.


Hi Richard: I just inherited a  5 gal. tank. I stocked it with fresh water fish: i.e., 3 small danios, 1 cory catfish, 2 pink glo-fish. They are non-aggressive & get along fine. (a) can I add one more fish like another glo-fish[blue or purple] or small dwarf gourami? (b) My 5 gal. tank is well aerated; water remains clear/I feed either flakes, a small portion of algae tabs for the cory. None are keen on the Fried Dried shrimp. (c) can I substitute freeze dried daphnia?. Hope these inquiries aren't too challenging. Whatever you wish to answer is fine!! thanks, Ken

Hi Ken

Your tank is overstocked as it is. Unfortunately, a 5 gallon is only large enough for 4 small fish (1 - 2 inches in length)

In addition to the flakes, you can add bloodworms a couple of times a week. The algae wafers are perfect for the Cory.

Hope this helps, good luck!

I own and maintain several freshwater aquariums from 2 to 180 gallon. I can answer most questions about freshwater aquariums, including setup, cycling, maintenance, compatible tank mates, feeding. Moving? I've moved fish both across town and across the country and can help you get your little aquatic friends to their new home safely. I know and have experience with most freshwater community fish, South American Cichlids and African Cichlids. I don't answer questions about Goldfish or keeping Goldfish with Tropical Fish. I also don't answer questions about keeping crustaceans (shrimp, snails, crabs etc) with Tropical Fish, nor questions about saltwater fish or aquariums. I'm not available to answer questions on weekends, this is when I do maintenance on my own tanks.


Many years of personal experience with community tank fish, semi-aggressive fish (Barbs, Tetras, etc), Angels, South American Cichlids and African Cichlids.
