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.
But, if you're desperate.. You can give the betta little bits of food like raw shrimp or worms you find, but very little, and if he doesn't eat it, remove the pieces. Tuna fish, little bits of fish fillet, you can try soft vegetables like a cut pea.. Further communication on this topic has been disabled.
