Their natural habitat is the slow-moving or not moving at all swampland and paddy-field of the far East, where water levels vary widely across the seasons, so that from time to time they find themselves living in little more than a puddle, and at others they have a huge lake to swim about in. Sadly, many unscrupulous dealers have used the former conditions to justify them being sold in tiny plastic cups and jars, when of course to live healthily they need much more space, though their resilience to less than perfect living conditions has undoubtedly contributed to their massive growth in popularity. Unlike any other popular small fish, betta fish need to be kept alone.
I just want to make this very clear from the very beginning. No, two betta fish should not live together. If you think, because two betta fish are alike especially with environment requirements and food , they will best live together.
That is not true, especially when talking about two male betta fish. Betta fish are very territorial. Besides the fact that the two male betta fish will end up fighting and hurt each other, just the fact that they are sharing the same space will stress them out greatly.
And a stressed beta is more likely to fight with its stressor. Unlike its male friends, female betta fish can live together in the same tank. A tank with multiple female betta fish are called betta fish sorority tanks and they look pretty. However, they are still aggressive and territorial.
So even though it is possible, it is difficult and takes lots of efforts and attention from the owner.
A Checklist for Starter As you learn more and more about betta fish and your fish, in particular, you would know what works best for your fish and you can add or take out what you need from the checklist. But for now, here is a simple checklist to start off your search to find a tank mate for your betta.
No nibblers or biters: betta fish are aggressive by nature. They can attack another fish just for being in their area. So you can imagine the outcome if they live with another fish that often bites.
If a fish nibbles at the betta, they will get bitten back for sure. No bigger fish: bigger fish can appear intimidating for the betta.
No more colorful fish: similar to sizes, a colorful fish can be intimidating for betta. So you also need to avoid getting a colorful tank mate for your betta buddy. Check aquarium size: betta fish are very territorial. Regardless of how many fish are in the tank, the betta fish alone needs at least 5 gallons of water space for itself.
Check bottom feeders: bottom feeders are great fish to live with betta. Most of them can happily cohabitate with a betta fish. Check them out to see if you would like a bottom feeder in your tank.
Dietary requirement: remember to check the dietary requirement for both of your fish. Your other fish may or may not have the same dietary preferences and requirements like your betta.
It is important to give both you fish a good and healthy diet. Cross-reference their diet to make sure that a thing that is not harmful to one fish will not be harmful to the other as well.
Tank ornaments: Sometimes the cohabitation of the two fish in your tank can be nurtured further by you.
Add a few tank ornaments and live aquatic plants. In case, once in a while, a fish is intimidated, it can have some places to hide. As you can see from the checklist, it is actually not that difficult to find a tank mate for your betta fish. Most of the fish that can satisfy the requirements in the checklist above are likely to be fine living with a betta fish.
However, if you are looking for some concrete guide instead of a general guideline, here are a few specific suggestions of the types of fish that can cohabitate nicely with betta.
Neon Tetra Neon Tetra is the mid-tank area type of fish. Normally, they would keep their distance from the betta so they can get along quite well. Neon Tetra is vibrant in color.
Together with your betta, they will make your tank look very vibrant and colorful. Betta and Neon Tetra in gallon tank peaceful! Bristlenose Pleco They are usually pretty shy so they tend to be very reclusive.
