I'm so sorry. Don't blame yourself for not knowing, maybe he was just plain old. Bettas average lifespan is between 3-5 years, but only if taken proper care of. You made it into the proper care years! Besides, he was with you for 4 years, but was he 4 years old? Maybe he was 5 or even 6! So, maybe ick was part of it, but he was an old Betta so don't blame yourself. He got a good home for the majority of his life.
If guppies are jewels, than Bettas must be rainbows
