I've had a few betta fish over the years and never had one this spoiled before.
My buddy Steve ignored pellets from day one. I tried to push the issue for a few days, but the most he would do was chomp on it and spit it back out (These aren't huge pellets either. Previous bettas just crunched them down.).
So after a few days, I panicked and fed him brine shrimp. He ate plenty, the porker.
Then it was back to ignoring pellets.
He eats blood worms just fine.
So the question here is -- How do I get him to eat the pellets?
As much as the brine shrimp are "gut stuffed" with nutrients, I'm fairly sure blood worms and shrimp wouldn't be a balanced diet.
Has anyone else had this issue? Is the only answer to keep buying pellets until he accepts them? Is it possible the food went "stale" after being in storage for a year?
