Standard Deduction Vs. Itemizing. Adjusted gross income has nothing to do with itemizing, which is a common mistake may people make. The section on Form 1040A following Adjusted Gross Income is titled Tax and Credits and includes Line 40 for itemized deductions and Line 42 for exemptions.
Bettas being kept as pets will do well on a standard pellet food designed especially for bettas (I recommend HBH Betta Bites or Tetramin granules) with an occasional treat of frozen/live worms or freeze-dried brine shrimp andbloodworms. Pet bettas should not be overfed; a few pellets per feeding is sufficient.
Put two males in a tank, and one of them will kill the other. Females aren't safe, either. When a male isn't interested in breeding, he might do in a female betta. You do need fish experience when breeding bettas, because putting the male and female together at the wrong time can lead to disaster.
