I recently got a blue and red fantail betta for the first time and have him in a 1 gallon rectangular tank with 1 ornament, filtration and a light. He seems to be doing fine after 2 weeks. His color has improved and he is lively. We put a mirror near the tank so he can see his reflection.
The pet store we got him at suggested the small bites pellet food and said to feed the betta 6 - 7 pellets every 3 days. But when I got home and read the package it said to feed 1 - 2 pellets once a day.
Which method is better for the fish?
