How many Bettas can I put in my 10 gallon aquarium?
When you hear this you’re probably like
Duh
But you’d be surprised how often we see that. I swear it’s once or twice a week someone’ll ask “Can I put all 3 of my male Bettas together” or “Why do my Bettas keep killing each other”
The answer is 1 male Betta in a tank, it’s always 1. Unless you put a divider in the tank, then it’s 2, 1 on each side.
I’ve always said a Betta should be kept in at least 5 gallons so if you put a divider in a 10 gallon you now have 2 5 gallon tanks so you can have 1 on each side.
Just make sure they can’t see each other through the divider, it stresses them out.
But let’s take this in a different direction, let’s get controversial.
You do have the option to have multiple females in a tank. We call it a Betta Sorority.
Female Bettas are a lot less aggressive than the males but this can be really tricky cause they can still be pretty nasty and you wouldn’t wanna do this in a 10 gallon.
The truth is a lot of times when people ask the question how many can they put in a 10 gallon they’re asking about the females and my answer is always the same.
You can’t do a Betta Sorority in a 10 gallon.
I recommend at least a 20 gallon and the maximum number I would do is 5 females and there’s several reasons why.
First is if the girls don’t have room to get away from each other they’re more likely to fight and the next is you’re gonna wanna have some dither fish in with them to also help curb the aggression.
If you have 5 girls in there with 6-8 little dither fish that’s a lot of fish crammed in a little 10 gallon, plus they’re all on top of each other all the time. You’re asking for trouble.
If you double the size of the tank to a 20 gallon with the same number of fish there’s plenty more room for them to get away from each other. It just gives them more room to spread out and relax rather than being up each others butts all the time.
But wait Lisa, you said dither fish…. what’s that?
Dither fish are other fish that’ll give the Bettas something to focus on rather than constantly thinking about wanting to fight each other. Plus it adds more activity to the tank.
There’s two more important things that you need to know when it comes to keeping Bettas and this applies to keeping 1 male in a 5 gallon or 10 females in a 75 gallon with 12 dithers.
You need plants and you need to keep them fed.
The plants will be something for the fish to explore through while also giving them places to retreat if things go south. I’ll be doing a video in the next couple weeks revealing the top 3 plants for Betta tanks so be sure to subscribe with notifications on so you don’t miss that one. Also feel free to leave in the comments other Betta specific videos you’d like to see. I can all day about these fish.
And keep them fed, there’s only a few things that fish fight over and food is one of them.
A well fed fish will be more relaxed, less stressed and less likely to be looking for a fight.
So if you’re gonna do a sorority make sure it’s at least 20 gallons with 5 females, some dither fish, plenty of plants and keep their bellies full.
But the original question was how many Bettas can go in a 10 gallon and the answer again is 1, it doesn’t matter if it’s a male or a female.
So there ya go, I hope you got something out of this video and are enjoying the quick tips videos cause I’m sure enjoying making them.
Don’t forget if you wanna support the channel you can do that by checking out our website….. you might not know this but we sell Bettas and we’ll ship them right to you.
