This is my first post on this forum.
I am a relatively experienced aquarist. I have been seriously keeping fish for the last 2 years, and I have kept everything from rare piranhas to angelfish and dwarf cichlids along the way. I currently have 3 tanks, 37g with a breeding pair of Archocentrus centrarchus (and friends), a planted 29g south american tank with dwarf cichlids, flame tetras, and cory catfish, and a 2 gallon hex with one male red crown tail betta. He's the reason I'm here.
I kept bettas when I was kid, but I didn't really know anything about them. I visited SE Asia last year and I was amazed at the plakats I saw in the markets. I picked up a betta just recently on an impulse buy to fill a vacancy left by the passing of my wife's goldfish (she shouldn't have put it in such a small tank to begin with), and I have been captivated by the little guy ever since.

1 light not sure the wattage or lumens (came with the tank)
1 big sprig of Anacharis that provides some cover
I haven't picked up a heater yet. It hasn't been an issue as of yet because I've been keeping the heat on in the bedroom where my betta is, and the tank temp has stayed above 75 degrees consistently, but I know he needs a heater pretty soon.
What kind of heaters do you guys recommend for a 2g hex?
Also, I tried to feed him some Omega 1 betta flakes but he ignored them. He also ignored the NLS cichlid pellets I feed my cichlids. He went a few days without eating, so i offered some tetra flakes and he snapped them right up. I know this isn't the proper nutrition. What should I feed him?
Any and all advice would be much appreciated. Thanks in advance!
