I'm currently feeding my betta HBH Betta Bites, but it's a bottle from about 15 years ago. In the intervening years, the new forumla has changed:
- -5% protein
- -9% fat
- -3% fiber
- +2% moisture
- pellets doubled in size
Top 3 ingredients changed from fish meal, fish oil, blood meal and ethoxyquin to fish meal, wheat starch, krill meal
I have some NLS Growth coming next week, which I picked primarily because it doesn't have ethoxyquin. I've been feeding my betta the ethoxyquin-laced pellets because of the protein content and he's still healthy and alive (I didn't realize it hat ethoxyquin til sI started typing this post)
IMHO, the ethoxyquin angst comes down to the fact that it's a toxin and people (including myself) are concerned about feeding it to our fish over a long period of time.
