Danios can share their aquarium with other community aquarium fish of similar size and temperament. Instead of plants, they eat aquatic crustaceans, worms and aquatic insect larvae. Danios are schooling fish and like to swim in groups and should be kept with three or more other fish of the same species. You will see them swimming in the middle of your aquarium. To create a beautiful aquarium environment, be sure to add some top and bottom swimmers as well. Ask a PetSmart associate to help you choose.

Rasbora Heteromorpha is rated 4.7 out of 5 by 26.
Rated 5 out of 5 by from Amazing Fish I have a small school of Rasboras and they're amazing fish! They are docile, beautiful and moderately active. I just wanted to note that the PetSmart care guide for these fish states the lifespan as 5 years, but I have had one of mine for 8 years. These fish are very hardy! Overall, they're an excellent addition to any tank.

Rated 5 out of 5 by from Peaceful Fish These are great fish. Fun to watch and very peaceful. They haven't bothered anything in my aquarium and are fine with my betta. Their movement is smooth and they are not as hyper as other small fish. Their coloring is much nicer than is shown in pictures.

Rated 5 out of 5 by from One of my Favorites. These fish are my favorite community schools. They are very active and full of personality. IMO one of the coolest features about this fish is that they also have distinct individual features and personalities, so it's easy to recognize and keep track of each fish.

Rated 5 out of 5 by from Awesome fish! I have a school of 5 rasboras and have had them in a 10g with two red honey gouramis for about a month now. All 5 are healthy, active and get along great with all their tankmates. Most of the time they stay together in pairs or as a group, so I'd definitely recommend getting at least 5-6 to make them more comfortable. I noticed the description also says they are "top swimmers", but mine seem to spend an equal amount of time in the bottom, middle, and top areas of the tank. They're awesome fish and I'd definitely recommend them!

Rated 4 out of 5 by from mid-top swimmers These are fun little fish. Mine are mostly in the upper areas of the tank and adds an attractive addition to my aquarium. These little guys are jumpers though and I have lost several to their suicidal tendency. Keep a lid on, imo, with more than 6, as the numbers drop they can get nippy towards each other. I will find a lid for my odd aquarium and happily buy more of these guys.

Rated 5 out of 5 by from Great Schooling fish I have 10 of these guys in my 20 gallon aquaruim and they seem very happy. The more the marrier with schooling fish. These guys swim around the whole tank and explore on their own, since I don't have a large fish they feel safe. For anyone that wants to get these fish, I recommand a school of 5-6 or more. Keeps them from hiding.

Rated 5 out of 5 by from Great little schoolers! These little guys are a great beginner fish that are pretty hardy and can really bring some life to the tank. While I mention they are a hardier fish that can live through some of the learning curb suffered by most beginning enthusiasts, it is also best to not make the rookie mistake of only keeping a 1 or 2 of them. These are shoaling fish that are much happier in a group of 6+. Not only will a group of this size make the fish happier and in turn healthier, it is much more entertaining and impressive watching a group of them swim throughout your tank together. Personally I have 7 of these guys in as a mainstay of my 25 gallon tall tank community, and it is always fun watching these guys swim around in unison. They really love to put on a little show as many times I can catch them across the room just chilling and staying still, but when I come over closer to watch them it is playtime! As for care the temperature stated is good on this page, I personally try to keep between 78-80 in my tank. These guys are pretty adaptable to you tank parameters but try not to go on extremes with you pH and keep it between 6-7.5 and they should stay more than happy.

Rated 5 out of 5 by from Awesome fish. I love my Harlequin rasboras! I had five of them, and sadly 3 of them died after my filter (it was a top fin) started getting weaker. Well, after replacing my filter with the aqueon quietflow 30, I got 4 more for a total of 6 (in a 29 gallon tank), and they have done wonderfully. They have at least doubled in size since I got them and are very enthusiastic eaters. They are very peaceful, however and are very pretty little fish. I have mine with 2 mollies, neon tetras, a long finned blushing white skirt tetra, a rummy nose tetra, cories, a bumblebee catfish, and 3 otocinclus, along with 3 silver hatchetfish, a dwarf gourami and a mystery snail. They get along with everything else in my tank. I would definitely recommend these for any community tank!

Do these fish get along well with bettas?

Asked by: When Guinea Pigs Fly
Yes, they usually do. You should usually have 4+ of these fish so that they can live happily with your Betta.

can they live with male betta fish

Asked by: rince3
Yes, they are one of the best tank mates to put with bettas
Answered by: KenKen123

I was reading online these are the most compatible fish to place with Bettas. Because they live in the same habitat side by side, is that true?
