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 ofplants, 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.

Rated 4 out of 5 by from BRIGHT AND COLORFUL I bought these fish a week ago and I love them. They all get along very well except for one. He sort of nips at the others after meals sometimes. Otherwise, very good fish! These are schooling fish, so I have five and recommend to get at least 3. Now they live with my dwarf gourami and plecostomis. I would recommend this fish.

Rated 4 out of 5 by from great fish This fish is a very peaceful community fish. The only bad thing i experienced is it may be eaten by even slightly larger fish. Do well with fish its own size (guppies are good choice).

Rated 4 out of 5 by from Very Nice I bought 3 of these 2 years ago and all are still alive today! I would suggest getting more than 3 though just because they love to school and can get stressed out when kept in smaller numbers. Mine are about an inch and a half big! Would definitely suggest

Rated 4 out of 5 by from Good Community Tank Fish These little guys (and gals) are great. I have them in a tank with other kinds of tetras and some guppies. They get along with the other fish quite well. I don't have any "larger" fish in the tank so the neons don't look like food to anybody (lol). My neons like to school together frequently and enjoy one corner of the tank with a large weed as a hiding place when the mood strikes.

Rated 4 out of 5 by from Neon Tetra I love this little fish. They are always fun to look at but you need to make sure you have at least five neon tetras otherwise if you dont. they will tend to hide and not be active. But overall this a hearty fish that will be very calm and active and wont hurt or pick on other fish unless you have four or less.

Rated 5 out of 5 by from Great Hardy Fish! These fish are great little hardy fish! They live for a long time if they are in big schools! I have a school of 11 in a 20 gallon tank, along with 4 Cory cats and a dwarf gourami! They all get along great! I love that they aren't fin nippers, so it gives me a peace of mind that they can live peacefully in my 20 gallon tank with their tank mates! I also have housed them with bettas and have had no problems! Just remember, schooling fish need to be in schools of 5-6 AT LEAST! I recommend these fish to anyone who are just starting to keep fish!

I have a male fantail betta can neon tetra's share a tank with them

Asked by: Sfm23
I would not let the share a tank UNLESS you take your betta in a small container (like the ones in the store) and seeing if it reacts negitivly to the tetras. If it flares up and acts aggressive, I would say don’t House it with other fish. Lastly, you will need at least 6 tetra to have a betta community tank so that they can school safely. The betta needs space and you will need at least a 10 gallon tank for the 6 tetras and bettas extra space. The rule is usually 1 gallon per 1 inch of fish, but when putting betta with other (smaller) fish, you will need a couple extra gallons.  Tip: DONT place betta with any fish that have large fins, bright colors (like glofish), or are bigger than the betta fish. This could make the betta more territorial and aggressive towards the other fish.

which fish can share a tank with a betta in a 10 gallon tank

Asked by: Sfm23
I suggest non-Carnivorous fish that are not too large or over 2 inches. However, you can choose a Betta by doing the flare test (hold betta up to other bettas in the store and see if it flared up. A slight flare is okay) and choose the most docile betta to place with no less than 6 tetras! I have a betta community tank and I currently have 6 tetra, a betta fish, and a small sucker fish. I recommend a 10-20 gallon tank though! The rule is 1 gallon per 1 inch of fish!

What do you have that can share a tank with Betta Fish ?

Asked by: cp757
I have a Berta community tank and I recommend at least 10 gallons for a more docile Betta to share a tank with these fish. I also recommend holding the betta you want next to other betta to choose the one that flares up the least and seems most docile. You can also hold the betta you choose up to the tank of fish you want and if urban flares up too much, DONT get that fish species. I also recommend getting community fish that are similar in size and get at LEAST 6 tetra if you’re getting other middle swimming fish. I made the mistake of only havin three tetra at first and (to my surprise) the other species of larger tetra killed the runt (smallest) tetra! Make sure to get at least 6 tetra for your betta community tank so they can school safely!!!

Could five neon tetras go in my 20 gallon tank with my 4 female Bettas??

Asked by: Kat015
It all depends on how aggressive your bettas are. If you have nothing else in the tank and good filtration, I would recommend getting around 10-12 with some plants or caves for them to hide in, so the bettas can't single out just one and so that they feel more comfortable with in larger numbers.

Are neon tetras compatible with betta fish in a 5.5 gallon tank?

Asked by: 1029838
Your tank is too small for tetras because tetras need alot of space and need a group of 6
