Great for beginner aquarists, tetras are attractive, hardy fish that come in a variety of colorations and patterns. Tetras are an active, peaceful, schooling fish that mix well with other community fish. They prefer to swim in schools of five or more. Tetras can share their aquarium with other community danios, rasboras, catfish and less aggressive barbs and gouramis.

Instead of plants, tetras eat aquatic crustaceans, worms and aquatic insect larvae. Vary their diet by including frozen or freeze-dried bloodworms, tubifex worms and other small worms, mosquito larvae and daphnia. You will see your tetras swimming in the middle of your aquarium. To create a beautiful environment, be sure to add some top and bottom swimmers as well. Ask a PetSmart associate to help you choose.

Black Neon Tetra

Black Neon Tetra is rated 4.7 out of 5 by 105.
Rated 5 out of 5 by from Peaceful schooling fish I have a school of 6 neons in my 25g community with some glass shrimp, peppered corys, and a male betta. They keep to themselves mostly, but when bettas are involved you can't ask for better than that. Mine are a bit shy and like to hide behind a chunk of driftwood sometimes, but they spend enough time in the open to give the tank some needed color. Pictures don't really show how much the blue stripe reflects light, they're much more colorful in person.

Rated 5 out of 5 by from Every tank should have several Neon Tetras have always been a favorite of mine. These fish are very low key and they do well in groups of 6 or more. right now I have 8, but I'm looking to get another 8 shortly. They are schooling fish; however, they will swim out on their own and there maybe one or two that are loners and like to hid out and be by themselves. these fish are colorful and a joy to have in any tank.

Rated 4 out of 5 by from Pretty fish, little bit sensitive Great great fish. They're very cute, competitive eaters. It's normal to see them chasing eachother a bit, that's why it's so important to get 5 minimum so that they can safely disperse their aggression. The two main issues I have found with these fish is that they are quite sensitive to their environment. Very slight traces of ammonia can result in damage to their fins. Because of this I recommend you replace a minimum of 30% of your aquarium water once a week in order to keep the quality up, and don't ever get lazy about it. They also seem to be very sensitive to swim bladder issues. I overcame this simply by buying a higher quality fish food. Omega One freshwater flakes have high quality ingredients and when fed in moderation can be very beneficial to your fishes' health. Aside from that, very nice fish to have.

Rated 5 out of 5 by from Amazing Fish I originally had cardinal tetras and thought that they were the best fish ever, but the only problem with the cardinal tetras was that they were quite expensive. It was a problem until I found these neon tetras. They're almost the same, and any ordinary friends that come and look at your aquarium can't even tell the difference! I have a school of five now, and I love to watch them swim around my fish tank and chase each other. These fish are the best.

Rated 5 out of 5 by from Love Them I bought these fish a couple of days ago and i love them. They are a nice addition to my other tetras. They get along with all of my fish. They swim around my fish tank and it adds a nice pop of color to it since they are are bright with color.

Rated 5 out of 5 by from SO FAR SO GREAT! School of 8 SO FAR very good!!! Over two months! School of 8 with NO ISSUES!! OOPS!! Cycled with the neons! I was new..I didn't know to do a fishless cycle...I was crazy about water changes in my 20 gallon and tested h20 daily! ALL LIVED!!! Two months in - crossing my fingers! Paid $1.00 each for these! THEY LOOK SO COOL in a school! I also purchased the Marineland tank with "day" and "blue night light". At night-the neons have a little glow to the blue stripe! VERY COOL!

Do you carry ..perhaps a older black neon tetra? I want one to keep company to the one l have. .

Asked by: Marvic
They should be kept in schools of 6 or more. If you only buy one more there is a good chance that one of them would die and then you would only have one again.
