I had a 25 gallon tank that was a paladrium, it had some plexiglassed in land for a newt and 2 frogs and then mostly water with high amounts of plants throughout the tank. At first in the water I had my centerpiece which was a GORGEOUS betta, then I had 2 orange tetra and 2 zebra danios, this was an experiment because no one answered me at the pet store as to what would be best with the betta. I found the tetra and danios were stressing the betta, the tetra were nipping the tail of the betta and the danios were zipping around him too much. I moved the danios out first because they also ended up scaring the tetra but then the betta died, I tried again with mollies and it went well so that would be my BEST suggestion. In your size tank I would half lots of plant life on one side to leave the betta a place to live and a few mollies not too many in a 10 gallon though I really wouldnt do more than 4

I have had two female bettas in the same tank for almost a year, they dont seem to bother each other.

Well, it depends on what kind of betta, male or female? If it is a male you can’t really have it with anything else. You can have some algae eaters, i have a couple ottos with mine. If you get ottos, make sure you get at least two because they like to be together. Also, my two ottos hide most of the time because my betta kept picking on them. So, it depends on the personality of your betta.
Besides several different kinds of algae eaters, there’s not many other fish that can go w/ him. Deffinately no fin nippers, aggressive fish, or top swimmers. The only thing you can get to go with a male are peaceful bottom dwellers, such as algae eaters.
However, if your betta is a female, you have a larger choosing of fish. You can have just about any peaceful fish with a female betta. If you choose to have more than one female betta be sure its at least three. Never have two females together because one can become the alpha and pick on the other.
Hope this helped, feel free to contact me if you have any further questions.

Bettas are called Siamese Fighting fish, but they definitely WILL NOT kill anything you put in it. They are compatible with:
- Corydoras
- Minnows (danios (even long finned), white clouds)
- Loaches (VERY cool)
- Mollies (with shorts fins, no lyretails or ballons)
- Platies (boring, but safe)
- Plecos (if you like that sorta thing)
- Rasboras (pretty cool, schooling)
- Swordtails (no high-finned!)
- Tetras (schooling, so you could have about 10 neons in there. You can always fit in many small ones or a few big ones. Neon tetras are cool looking and their bioload is less than their equivalent inches, so you can fit A FEW more than the inch-per-gallon rule permits.)

You can have almost any peaceful fish that doesn’t have long fins. They’ll think that its another betta and immediately start attacking it.

If i were you, i would go for a dojo loach or two and a small school of either tetras or rasboras. And maybe a mystery snail and/or a shrimp (bamboo, cherry, amano, ghost, or otherwise, theyre all pretty sweet).

Just make sure that your tank is ready for it. You need to cycle it first so that the bacteria in it can support a bigger ecosystem in your tank. Test your water at your local fish store before adding any new fish.

I keep my betta in a 15 gallon with a school of 8 cardinal tetras, a group of 4 corydora catfish, a couple of amano shrimp, and a trio of Oto catfish.

Despite what you hear, betta’s fit in well with many types of community fish. Unfortunately the idea that they are mean killers is one of many myths that continue to be spread by parrots who just like to repeat what they hear. And there are plenty of parrots around.

Make sure you provide lots of plants – it provides cover, breaks up territory, and encourages natural behaviour, roaming and activity from your plant dwelling fish (bettas are pure plant dweller and do NOT belong in empty little bowls).

Avoid other bettas and fish from the same family, like gouramis, as they will probably fight. Also avoid fish with splendid finnage, like fancy guppies.

Avoid aggressive fish that might pick on the betta, like danios, tiger barbs, and serpae tetras. Believe it or not, people run into more trouble with aggression toward the betta then from it!

Avoid adding single fish, which might be targeted by the betta. Keep the rest of the inhabitants in groups, which means schoolers are best. 6 neons would work, but just 1 neon would likely end up killed (or ill from the stress).

This seems like a lot of warnings, but in the end it leaves you with all sorts of calm, peaceful fish that would work well. An example for a 10 gallon might be 6 neon tetras and 3 corydora catfish or several ghost/cherry shrimp. Don’t worry too much about the inch per gallon rule – it’s not accurate in any way. Fish like corys, shrimp, and neons are so light on the bio-load that you can fit more than that, while for many other types of fish that rule isn’t nearly enough to work.

Here’s some other myths about betta’s that I can clear up for you once we’re on the subject:

They don’t come from puddles in the wild, they come from rice paddies, ponds, streams, and rivers. Some of these are oxygen deprived at certain times of the year.

They don’t rely on getting air from the top of the water and have gills like any other fish. They can’t drown, and their ability to breath air is not an excuse to keep a fish in an oxygenless bowl.

They do like tight spaces and get stressed in the open. Real fish keepers accomplish this by putting the betta in a tank with lots of plants. Amateurs do this by stuffing them in a tiny, stale bowl.

Betta’s in the right setup are very active fish. People think they are inactive so they put them in a bowl – they don’t realize they are inactive because they put them in a bowl! Betta’s also live for over 5 years, not the 1 or 2 that people tend to think.

Hi bettas make good tankmates with fish that don’t have long fins (fancy guppies for example), can’t eat them (oscars), aren’t aggressive (certain cichlids) and aren’t coldwater (goldfish).

Some good fish to try are:
Tetras (can nip fins)
Rasboras
Otocinclus
Dwarf Plecos (zebra, clown, bristlenose) (need at least a 15 gallon tank)
Corydoras Catfish
Platies
Pencilfish
Danios (can nip fins)
Bamboo Shrimp
African Dwarf Frogs
Loaches

For your tank, I would use the betta as a centerpiece, and maybe have a small school of 7 neons, and a trio of otocinclus or corydoras catfish. I think that would be a cool tank with some good activity at all levels of the tank.

Other fish to avoid:
sharks (can be aggressive, need larger tanks)
tiger barbs
silver dollars
angelfish (need large tanks, might bully the betta)

I hope that helps and good luck on your tank!

Make sure your tank is cycled first.

Bettas go well with other tropical fish that don’t look anything like them and aren’t fin nippers.

The do especially well with bottom feeders like corydoras and otos.

You should keep the inch per gallon guideline in mind when stocking a tank that small. Your betta is 2.5 inches. You can put four or five oto’s in that tank.

You can always add as many cherry shrimp as you want because they’re so light on the bioload.

Do some research on the nitrogen cycle and the bioload and how they work together.

If you mean Beta as in the japanese fighting fish then nothing.
It will most likely kill anything you put with it.

I always like bettas with neon tetras. They’re smaller, so they don’t usually cause the betta to fight with them.

Avoid fish that are the same size and/or brightly colored.
