Housing 3 male betta fish in 1 ten gallon tank

Housing 3 male betta fish in 1 ten gallon tank
** Disclaimer: **

Please use caution when dealing with male bettas.
Do not put them in an undivided tank, or they will kill each other.
Always use care and common sense when dealing with your fish.

You may have bettas that are just the opposite of mine. This method, and the information contained in this instructable, is from my personal experience and online research.
I take most online information with a grain of salt, except for the information on Instructables, of course !

Here's a quick example: Online, I read that bettas do not like currents, since they live in puddles in their native habitat. This rules out the use of most filter units that work well.

My experience: I turned on the filter, which makes a current, and the betta investigated it, swam around in the current, and had no problems.
I keep it on the lowest setting, but still, all 3 fish have been in with the filter, and after a 30 second initial investigation, they have no problems with the filter or the current.

**** BACKSTORY ****

Well, I had a betta in the past, but one day he got his feeler caught in the marble-shaped glass beads on the bottom, pulled part of it off, got an infection and died.
He was a great fish, with lots of character (for a fish).

After that, it was about 5 years before I tried again. My girlfriend and I were shopping when we found 3 (yes THREE) betta fish. We couldn't decide which one we liked best, so we bought all of them, and housed each one in a separate glass vase.

Fish #1 (sail) and Fish #2 (poof) were in 1 gallon vases, and Fish #3 (shadow) ended up in the former betta's 2 gallon vase.

**** WARNINGS ****

I know that a lot of people say that these fish don't need a filter, swimming space, food,
and all kinds of other crazy stuff.
They may be able to live in a very small jar with no filter, but is that healthy for them ?
Do they like it ?

I say ======> NO !

The plant idea is also junk. These fish are meat eaters, and at some point they will nibble at the plant's roots when they are starving. The betta in a jar with a plant and no food is a BAD idea.

You have to maintain the roots and leaves of the plant to keep from having dead roots in the water, and you still have to feed the betta !

**** Back to the BACKSTORY ****

Long story short, it became a major pain to clean all 3 vases every 2 weeks. I tried a little filter that worked on the movement of air to draw water through the filter. It didn't really do much, except amuse the fish, and if you moved the filter (to clean it) it would release all kinds of junk back into the vase.

So I hit craigslist and purchased a 10 gallon aquarium with a stand and light for $15.
What a deal !

I had already seen aquarium dividers at the pet store, so I was ready.

Well, I thought I was ready !

Step 1Buy the components and set up the aquarium.

Buy the components and set up the aquarium.
I cleaned the aquarium and rinsed it thoroughly. Then we headed to the pet store to pick
up the dividers (I needed 2)

When we arrived at the pet store and examined the dividers more closely, we realized that they were clear.
If you're not familiar with bettas, then let me explain.

If they can see each other they get very aggressive and try to attack each other.

I asked the guy that was working at the (commercially owned pet store name here)
if there would be a problem with the dividers being clear.

He said 'absolutely not'.

He went on to inform me that after a few hours of seeing each other, the fish would calm down and there would be no real problems.

Not fully satisfied, I purchased the dividers anyway, and some small aquarium gravel,
(NEVER use the glass flat marble rocks - unless you want a dead fish) then headed home.

** These instructions come with the divider **

The setup was pretty simple. Trim the divider panels to fit, put the side channels on the divider panels, fit the stabilizer channels on the top and bottom, slip the entire assembly into the tank, then fit the clips over the outside of the tank and down into the channels to hold the panels in place.
**************************************************

The illustration shows you sliding the divider panel down into the channels, but the material is too flexible to do it that way.

Once the dividers were installed, we put the gravel in, then the plants,
and then (slowly), the water.
After about half the water was in I put the recommended water treatment in, then finished filling the tank.

Then I installed the filter, an Aquaclear power filter 20. It was the smallest one that seemed to have the best multi stage filter.

Anubis--This is a wonderful instructible. I'm happy that you upgraded your bettas. Having had bettas in the past, I can tech support one of your problems. When you moved them from their individual "puddles" they had been living in, and moved them into closer quarters, they began fighting over territory. In their homeland, they live in heavily planted areas that divides them up into natural territories of pockets of small pools of water. When you upgraded the size of their pools, you missed the critical step of upgrading the greenery that helps shield and define their territory. Bettas are actually happiest in a heavily planted aquarium. (Not under plants, but amongst them.) If you add things like Java Fern, water onion, certain types of lily, and many other very easy to grow aquatic plants that all live below the water line, not only will the fish be happier, and thus healthier, but it will also mean that your aquarium water is more stable, as the live plants help filter the water and also cut down on the growth of algae. Best of luck with your fishie friends.

Wow, nice work looks great.

Since I'm a tad lazier, I'm trying to house two bettas on opposite sides of the tank (with 2 dividers straight from Petsmart). I'm hoping that putting alot of plants in the middle section will obstruct their view. Will this work?

  Okay. Here goes. I'm pretty new to Betta's. I ended up with one at a White Elephant Gift Exchange. LOL. I have 3 pet rats and so I tried to give it away (though I really wanted it), but couldn't. So, alas, with Christmas money I bought him a bigger tank, 5 gallons to be exact. It was the best tank I could find for a filter and light and had GREAT reviews for Betta's (I'm really obsessive about getting the best of best and all the correct information before I buy something).

 So anyways... I want another one. Haha. I got the Eclipse 5 Hexagon tank because I needed something that would fit in my room. I kinda wanted the standard rectangle they had in the same brand, but again, I needed something that was a space saver. So now I have this oddly shaped tank and I want to split it so I can add another Betta. This makes me wish I hadn't given away my 10 gallon tank a couple months ago though... oh well.

 Anyways, I had no real point to this comment. I just wanted to thank you for the ideas. I saw a Betta at Wally World that I want. Most of them looked very sickly though. *sigh* Do you have any suggestions on a better place to buy a Betta? Petsmart's seemed okay and I know there is a Petsupermarket nearby. Btw, your tank looks really great! :)

how did you set up your filter? I tried the divider thing because I had a female that was VERY aggressive and the other female was passive ... or ... terrified. my divider appears to be the same brand or whatever but isn't clear it is opaque. So anyway ... I do have and use a powered filter but even though the divider is perforated it only filters one side well. Actually I once had a pair that successfully spawned and hatched a brood in an undivided 10 gallon tank with a powered filter. .. with no "spawning leaf" or other apparatus to boot ... they also had a tankmate .. a "fresh water lobster" whatever that is LOL

your female could be an immature male, they aren't supposed to be aggresive, or she might not have enough room
Apr 17, 2009. 8:37 PMhandysmurf says:
naa she became bloated with eggs ..... definitely female
Sep 13, 2009. 1:25 PMkrissilion says:
Are you sure you not just feeding it to much?
Apr 18, 2009. 7:21 AMbassmonkey says:
that's odd, how many gallons is your tank?
Apr 18, 2009. 1:57 PMhandysmurf says:
10
Apr 18, 2009. 6:08 PMbassmonkey says:
hm. your a tough case (not an insult) so i would (a) get a 5 gallon tank for her (b)sell/give her away (i am not that kind of person, but it's an option) (c)get slightly bigger tropical fish than your Betta. i'm not sure this would work, but even fish have to pick their battles

the reason the bettas started getting mad is because they are natural fighting fish there real name is chinese fighting fish
Sep 13, 2009. 1:24 PMkrissilion says:
Hahaha. I am sure the person with 3 of them knew. In a week I am getting a 10 gallon just for 1 betta. =]

Good instructable. I use the clear dividers for females. They are relatively cheap and the females will eventually get tired of each other. Some breeders have even kept females together without separation. (Never attempt it with males!) FYI Some PVC can be highly toxic because they leach plasticizers into the water. There seems to be a problem with older PVC pipes, but new plasticizers have corrected it in newer pipes. I would be cautious with the siding. I'm pretty sure PVC siding is not as regulated as PVC water pipe. With regards to the fish, I personally don’t filter a Bettas water unless I am breeding them. I had one fish that would have nothing to do with the filter. However, I do aerate at a low speed during the winter to keep the water moving because I heat the small (1-2 gallon) tanks.

When you do, you should totally make an Instructable. Thanks so much for making this one! The initial solution I think was pretty genius, as well as some of the ideas from the comments. Now I think I need to hide my debit card so I can't buy more fish... XD

wow you are so so so so so so intelligent I would have never thought of that

Nice article, the Vinyl siding you used is used for the soffet under the eaves of the roof.

I have a betta and I found that sometimes you can have males with clear dividers but they have to be natural calm if they very aggressive when you got them its not the best idea to house them with clear dividers

I really like what you have created. I have wanted to have a pair of bettas ( male and female ) in a large tank togethor, but never could think of a way to do safely. This is giving me tons of ideas. Thanks for sharing.

Plastic canvas (available colored or clear in most craft stores or large "everything" stores) does work great. It is not toxic to the fish but allows the water to flow freely. Yes, female bettas do wonderfully in a sorority tank. I have all of mine housed in communal 10 gallon tanks. I personally do not use gravel or rocks of any kind in my tanks. Waste becomes trapped in it no matter the whether you have a filter or not, and it is a haven for bacteria. All I have in my tanks is java moss. It aerates and filters the water, plus provides safe hiding places for the fish. I just toss in huge clumps of it. And it grows like crazy, so I always have lots on hand. Plus, it seems to be like some sort of betta miracle grow or something. All of my home-bred fish, and even my puny little store bought few, are robust, beautiful, and HUGE, with almost no care other than feeding and water changes. Really, each of your fish has access to 10 gallons of water. The only real problem with housing your fish like this, however, is the old "one gets sick, they ALL get sick"...

how many females do you have in one ten gallon tank? i want to put mine together but i'm afraid they'll kill each other.
Dec 13, 2008. 9:31 PMbobhill125 says:
females dont kill each other only males do
Oct 6, 2008. 12:18 AMliquidsunshine says:
Females are generally not aggressive toward each other, and a rule of thumb is an inch of fish (length) to a gallon of filtered water, although I'm not certain if this applies with bettas. I know that you need twice the amount of water for "dirty" fish like goldfish.

Got a easier and better looking solution for you. Goto any good hardware store and ask for a replacement difusser cover for a 4 foot drop ceiling light fixture. Cost is about $4 and is clear enough to let light come thru and easy to drill for water movement if needed but will blurr the vision of the beta's enough that they won't see each other.
Sep 28, 2008. 1:50 AMCrucio says:
If you want to re-use your original dividers, you can sand them. That'll give them a nice frosted glass look, blur them, and allow them to pass light. The blurring should make the bettas unrecognizable to each other and hopefully end hostilities.
