if you are gonna go with corys in the 20 long get alot more the 3. they are schooling fish, and 3 is the ABSOLUTE minimum. Ive seen alot of people with 6 in a 10 gallon, so i would start from there and move up. the more of them they have, the happier they are, and they will show their schooling behavior which is cool to watch. 1 side note on introducing everyone. take your betta out, rearrange the tank a bit and add the other fish first, and give them some time to get comfortable. If you were to just add the cory cats he is going to be aggressive because he thinks the tank is his territory and that he has to defend it. if you rearrange it he will think it is all new and thus not his territory. it will cut down on his aggression.

8-10 cory cat's, white clouds, neon tetra's, danios, bushynose pleco, all these will work.

I only have 1 betta left, but he's a cool blue marble!

Platies may work too. My betta did fine with them.

Hi. I've had bettas for 3 years now and I can honestly say it depends on each individual betta as to what fish can coexist with them. I personally have a tank consisting of 1 male and 1 female betta, 5 glowlight tetras, 2 neon tetras, and a placo. They are all happy and coexisting fine. The one rule I have found true for all bettas is NO fancy tail fish. Anything with a long tail is asking for trouble from a male betta. :)

My betta is still the lone occupant of our 20 gallon long. Eventually, we will probably add some tank mates. He is by far my favorite fish. What a personality bettas have. His tank is on a desk and every time you sit down he rushes over all excited to greet you.

I have an empty 5 gallon planted aquarium and I am debating about getting a betta for that tank too. They are such fun fish.
