My male betta started staying close to the top of the water with his mouth very close to the surface, getting air every once in a while, and sometimes blowing bubbles. I thought he was making a bubble nest but he doesn't seem to be very energetic and isn't focusing on a nest.
I just did a 50% water change just in case the water wasn't fresh.
Also, in the tank are 4 snails (2 medium and 2 tiny) and a small pleco.
It is a 10 gal tank with filter (one size down from tank size) and heaters (keep the tank at approx 79)
My betta is fairly new and was energetic during the day time when I first got him.
He shows no other symptoms besides lethargy and favouring the top of the water.
What could be causing this?

Please fill out the entire form. Every question on there is important in assessing a Betta. We also need at least one photo. Thank you.

That wasn't the entire form? And I don't have a photo at the moment, as I am not at home. Please just give me suggestions.

Oh, sorry. I did the "undo" (ctrl+z) action and must have hit it too many times.

It's very hard to give informed suggestions without a photo, too. However, a low temperature of 75 will cause lethargy; also, if your Nitrite is .5 *after* a 50% water change it was high enough to compromise your boy's immune system. I would suggest three things:

1. Get a liquid Ammonia test. The Ammonia level is the most important parameter for an aquarist to know. Liquid tests are more cost efficient than strips and you'll be doing a lot of testing for Ammonia.
2. Get a bottle of Seachem Prime. It is dosed at two drops per gallon.
3. Follow this tutorial and cycle your tank. It also explains the reason for the Ammonia Test and Prime.
http://www.bettafish.com/30-betta-fish-care/507585-cycling-two-sentence-tutorial.html

When cycling a tank I do 25% water changes if Ammonia or Nitrite reach .25ppm; but .50ppm is okay. Once your tank is stable with 0ppm Ammonia and Nitrite and Nitrates under 15-20 you will only have to do one 25% water change per week at your current stocking. If you add more you will have to keep track of the Ammonia level for a week or two to make sure everything stays stable.

Good luck.
