I have a 20 Gallon Aquirum and one male Betta currently.
I bought a divider for the aquirum.
I have a filter and heater in there.
What fish could I put onto the opposite side of the divider?
I was thinking another male betta? or Neon tetras? or goupies?
Can those fish live side by side in a heated aquirum?
I have lots of plants currently in there and bought extras to go by the dividers so they can not see each other.

As well This is a picture of the aquirum currently with out the divider I plan to put the divider in this friday and leave it there for a week or so before getting the new fish so my current will be used to the arrangement.

Leaving the tank t it's full potential would more so result in the best actions and behaviors concerning your fish. Also we need to know a bit more information on your tank to properly creat a good list for you

PH, and hardness?
Tank dimensions?
How long has the tank been set up
Water parameters?
Tank temperature?

Tank dimensions? It is a 20 Gallon thats all I know.

How long has the tank been set up. I have had my betta in this aquirum sence January this year but hade it running for a few months with the heater and filter going before I got my betta.

Tank temperature? 78-80

How long, wide, and tall is the tank.
What's the PH, and hardness
What's the water parameters

We can't go depicting on what type of fish would suit this tank without vital information, as if you had very hard, alkaline water, will affect what type if fish that you could choose from

From the pic, it looks like a 20G TALL. I can be wrong but it does not look as long as mine which is a 20G LONG. No idea what the dimensions are for either though

I have chosen to hold off on getting another fish for a while I dont think it would be fair to take away half of his home when he is used to having the full to himself.

I agree with Mo, Xtina - I think it would be nice to leave the tank undivided and make it into a community. Some tetras and cories would be nice, if your water is right for them. Your local council may have information on the general hardness (GH), carbonate hardness (KH) and pH of your water. Mine did.
It is important to know these things as they do affect what tankmates you can have. For instance, most tetras will not live as long or be as healthy in hard water, whereas livebearers live guppies won't be as healthy in soft water. Some fish are also pH sensitive.

 

[xtina127]

I would not put other fish in with him he might hurt them I dont want that so he will have his home all to himself for the rest of his life. my next fish will have half of the 20 Gallon each from the start Two males bettas I think..

Actually, bettas can live quite peacefully with community fish, like tetras, cory cats, and the more plain colored guppies. As long as you dont put anything that looks like a betta in with him, he'll be fine. If you're really worried, then just put a school of cory catfish with him. They're peaceful bottom feeders that get along with most fish. Add in that bettas mainly stay at the top, though they will explore sometimes, and there's no real fighting. While my betta was a little worried over his guppy friends, he pays no notice to the cory. (I'm getting the rest of the school tomorrow; dont ever keep them alone!) Bettas are not vicious killers of all fish like some would have you believe. I was worried about adding fish to my betta's home, but they get along great and it makes the tank all the more beautiful.

I'm suprised at the given amount of people suggesting fish such as corydoras. This is very easy thing to remember that the majority of fish keepers know. They ideally should be placed in a sand substrate tank due to marbles, and gravel irritatin there bellies leading to fungal infection and wearing away there barbels

 

[SweetNightmare]

I am on my phone and thus cant see the pic of the tank itself. My post was simply to say that bettas are not killing machines to all fish, and that a community tank with a betta is quite beautiful. So is sand, while we're talking about it. I like it better than gravel, that's for sure. However, point being, the OP doesnt need to completely rule out tank mates just by dint of her betta being a betta. I added fish to my ten gallon and my betta is still very happy in his home. He flashes his fins sometimes at my guppies, but everyone gets along fine, no one chases anyone or tries to hurt anyone.

 

[Bombalurina]

Also, marbles would be fine for bigger cories like bronzes, Mo. Besides, a substrate isn't hard to change.

But if the OP wants to divide, that's cool. I'd just do two males, in that case.

Do what u want! I agree on the sand bottom with cory's, marbles are a tricky bottom dressing... Lot of un-eaten food. No tetra's in my opinion they r fin nippers sometimes! Maybe a smaller style catfish raphael or banjo or any that can't swallow the betta!

 

[Olympia]

I love banjo catfish. But good luck seeing one in your tank, they will squeeze under something and only come out at night they are tiny enough to have several in a 20 though.

 

[fishyy]

Any of the small, fast moving tetras are ok
