A male Betta can be kept in a 10 gallon tank with 5-6 neon tetras. You will need to monitor for any aggression initially as well as for any fin nipping. Male Bettas are easy to distinguish from females by their brighter colors and larger fins.

You can try it, however the Betta may flare at and harass the tetras from the other side of the divider to the exclusion of eating. Of course, he may do nothing also. It really depends on the fish. Neither species will do well in water with elevated ammonia or nitrite levels.

I want to put my male Betta and three neon tetras back in the same 10gal tank. The problem last time was that the stress level in the water was too high, so I separated them for a few months. Now I want to put them back together in the same tank, but

Can a male Betta be in a 10 gallon aquarium with other fish?
Hi and thanks for using Boop by Petco! Good question. Most Betta sold in pet stores are males and no they cannot be housed with other fish species because they will fight the other fish. They are also housed in 1-2 gallon sized aquariums or smaller aquariums by themselves since they fight. Good luck with your fish.

is a 10 gallon tank good for 7 betta fish
Hi there! The general rule of thumb is 1 gallon for each inch of fish, so I think that you may need a bigger tank. If the bettas are 2 inches each, they each require 2 gallons of water, making the minimum tank size 14 gallons. Since male bettas can be territorial and aggressive, I highly recommend a larger than normal tank with lots of hiding places for 7 fish (at least 20-25 gallons). You should also watch them very carefully for fighting, and have a backup plan in case any of them need to be separated. Good luck!

I am getting a beta fish and my sibling is getting glow fish. Do you have any suggestions as to a 10 gallon fish tank we can purchase with two separate compartments and an opaque divider? Thanks
It wouldn't be recommended. Bettas do best in little to know current, while Glofish enjoy more current and water flow. Additionally, Glofish are a schooling fish and do best in groups of 6 or more. If you split the tank, there won't be enough room. You would also need to keep the tank at the upper end of the glofish range (72F - 80F) since bettas do best in warmer water, 78 F to 80 F.

How to introduce betta fish to neon tettra, guppies
Betta are definitively very territorial and you may notice multiple fights for space at the beginning. Definitively the aquarium must have multiple spots for hiding like Terra Cotta Flowerpots and PVC Piping, moss or bushy plants, ornaments, rocks and driftwoods. This will avoid open fights and will provide good places to have some rest.

Hi, i have recently (as in today) got a betta fish and was hoping to get another betta, i only have a simple half gallon bowl for the fish and was wondering if there was a way to easily find a surefire friend for him without them fighting or being ag
If you put another male betta in with him they will try to kill each other and will succeed. You would need two female bettas to put in, however a half gallon tank is way too small for three fish, and even for one betta this is not big enough. I suggest you get a 10 gallon tank. Then you can put three bettas in the tank and they will be happy (1 male, two females).

I just purchased a baby male betta fish, can I put him in the same 2.5 gallon tank as my female, but with a divider?
You will need to use a solid or opaque divider to obstruct their view of one another. If they can see each other, it can stress them out. As the male matures, he will want to breed with the female and she will spend time swimming as far from the divider as possible to move away from him.

what kind of fish are these? and would they be good with a male betta
It is very difficult to see the markings of these fish from the pictures. Many fish may be able to live with a Betta if there is a large enough tank. Here are some guidelines on how to pick tabkmates for a Betta. No nibblers – if a fish nibbles at a Betta fish they will get bit back! Bigger fish and colorful fish could be seen to be intimidating – you don’t want to intimidate a fighting fish! Think of the size of your aquarium – you should always have 5 gallons of personal water space for your betta fish Many bottom feeders* are fish that can live with bettas Remember the dietary requirements for both tank mates Add a few tank ornaments and live plants for any intimidated fish to hide (just incase) You can find some more info here. http://www.drsfostersmith.com/pic/category_home.cfm?acatid=158

We have 2 guppies a betta and a catfish in a 10 gallon tank. The guppies recently started fighting and nipping at each other 1 took a chunk out of the others tail should we seperate them or take the betta out so there aren't so many alphas?
If the Betta is not acting aggresively, there is no need to remove him. Guppies, especially males, will fight with one another but it usually isn't serious. Providing plenty of cover for them to hide may be all you need. If the fighting persists, remove the aggressive guppy to his own tank.

What type of fish can I keep with my adult male betta fish, he is in a 3 gallon tank.
Most of the compatible fish are schooling fish that do best in groups of 4-8. This would include Neon Tetras, Ember Tetras, Harlequin Rasboras or White Cloud Minnows. That many fish may be too much for a 3 gallon tank. Other non-fish option include Ghost Shrimp, Zebra Snails or African Dwarf Frogs.
