Problems with 5 gallon aqueon-questions and bettas

I'll also have to agree with the others in that you must make sure your tank is properly cycled (usually I let it run through for 2 weeks to a month depending on the setup).

As for adding new fish for freshwater. Usually letting them float for 30-45 min in there bag is good enough. But to really ensure their health, I would still open the bag, clip it to the tank, and slowly add the tank water to it during the 30-45 min time span to ensure that not only temperature, but water parameters are acclimated for the fish as well.

To make sure it's seen. And to save me typing.

I do the adding more water at least twice, about every 20-25 minutes. About a third new water each time.
 
neons need to be kept at a temp of 82 degrees to live...
i imagine ur 1 gal betta tank wasnt heated and thats why they died...
u should be able to keep fish with him in a 5 gal as long as its heated,
1 gal is a tight squeeze to keep a bettas agression to a minimum..

I had the neons in the 5 gal and yes it was heated. The manager at Petco told me that ammonia killed them. I was ALSO unaware that you're not supposed to rinse out the carbon filter pad. I had separate chambers (canister filter) and I used to replace the foam fairly regularly, but never touched the biofiltration. Now I've learned that in a small set up they're the same thing!
 
in any filter you shouldn't be replacing the media (sponge, ceramic rings, etc) unless it is starting to disintegrate. all media is a surface for the bacteria to live on. when you go to rinse your media, do it in a bucket of water you've removed from the tank. rinsing media in chlorinated tap water will kill off all the beneficial bacteria and your tank will either have a mini cycle or will fully cycle all over again, resulting in high ammonia levels and fish deaths.
 
Bettas are cool little fish, but kinda tricky. They're personality may make them good candidates for community, but maybe they'll be vicious to anything they see. In a five gallon, one by itself is advisable. It's a good size for a betta, and should be relatively easy to take care of.

Otherwise, there are a range of possibilities for a five gallon tank. As I type, I'm looking at one on either side of my monitor here at work. One's a hex and one is a bowfront. In the hex I have some ghost shrimp, ramshorns and MTS along with two african dwarf frogs, two dwarf platys and a black molly. In the bowfront I have 8 or nine neons, lots of ramshorns and MTS and a bunch of red cherry shrimp. Both tanks are heavily planted.

Depending on what you want to keep, the thing to remember with five gallon tanks is water quality. Make sure you keep it clean. The fish I mentioned are relatively small, peaceful and don't create a lot of waste. Plants help keep the water clean and healthy.

Neons are great fish, but they die very easy, especially when you first buy them. Make sure your tank is cycled and ready before putting them in. Even then, you might want to pick something a little hardier. Guppies are good, but don't get a female or you'll be sorry. Likewise, pick fish that won't breed out of control on you, or you'll be in a jam.
