The tank was not cycled and leaving him in the bag for an hour like that probably resulted in a high level of oxygen depletion.

If you can get a bigger tank that would be ideal (not the cuase the the betta died), as 2.5 gal is really not good for any fish at all. I also use Seachem Prime as my water conditioner.

Here's a link for nitrogen cycle

Bettas are hardy fish though so it can also be that the fish was already sick to begin with.
This forum is great and helped me a lot. Good Luck!

Well water is fine. You do need a heater.
The problem was that cycling a tank takes weeks, not a few hours. The ammonia levels rose quickly in such a small tank and killed the fish.

What you did wrong was you didn’t cycle the tank properly. Just letting the water sit in the tank for 24 hours isn’t cycling. You need to add an ammonia source( bottled ammonia) as a food source for the bacteria to grow.Cyclig takes 4 -6 weeks

Hello @Jlsmith80!

With your size of tank you need to make sure you change it more often than a bigger aquarium to keep your water parameters at safe levels. I would read up on the nitrogen cycle that one of the members posted, and then give it another try!
Bettas are so much fun, and reallllly cute!!

Best of luck.

This is what I meant by bigger tank can be better, on such a small tank and not cycled water parameters can swing very fast and can be harmful to fish, specially when you accidentally overfeed.

Letting it cycle longer will keep ammonia levels down.

Yes it will keep the ammonia levels low if you cycle correctly. But it won’t cycle unless you start the cycle. I would suggest following instructions on a fishless cycle.
