"These are the first five ingredients in order of the tropical small fish food by NLS: Whole Antarctic Krill Meal, Whole Herring Meal, Whole Wheat Flower, Algae Meal, and Soybean Isolate. It says the crude protein is at minimum 48%."
Krill - yup, that's a 'meat' - protein
- Yup, that's a 'meat' - protein
Whole Wheat flour
- ummm, not a fish food - found in a lot of fish food, however.
I suspect it's the 'glue' that's used to hold the pellets and flakes together.
- veggie protein source
That doesn't sound bad, betta-wise. I note that my two favorite brands, Omega One and Hakari betta pellets also include wheat products and a veggie.
There are other options to feed your betta. The are the 'natural' sources like frozen and freezed dried worms, daphina and such... or live - you can raise your own brine shrimp, for example.
It's good to feed a mix of foods... a little bit of something different each day, so your betta gets a well rounded diet.
I personally have not fed my bettas anything but flakes and pellets (and ghost shrimp - but that's another story for another day). I'm worried about the frozen foods being spoiled - from partially thawing/re-freezing on its way to me. Live critters (worms, etc.) can harbor parasites and bacterias. So, my betta's diet is restricted in that sense - by my paranoia, lol!
My bettas get food from five different sources (including the low protein food I put in for the bottom feeders, which is more plant oriented). They are colorful and growing, so I'm not too
worried about them.
You'll find other betta keepers here on the forum have different food sources they swear by... so ask around, and see what they are using.
Also, one last thing... after about 6 months, any opened dry fish food may lose signifigant nutritional value... something to keep in mind...
