Yep, flow's a biggie. My guy was stressed till I cut the flow with a pre-filter sponge. Also, what's your water change routine? Even with good params, fresh water can perk 'em up.

Aqueon Pro's another good heater option. Just avoid the preset ones. Bettas need stability, and those things can swing temps. Also, toss in some Indian Almond Leaves for tannins. Helps 'em chill.

The PetSmart 5-gallon's a solid starter tank, but the heater's garbage. Swap it for an adjustable one ASAP. Also, throw in some Java Fern or Moss Balls to give your Betta hiding spots.
