Ok, so I’ve seen tons of posts hating on that, but when I first learned about frozen food I thought why wouldn’t you do that??? Seems closer to what they’d eat in the wild. I don’t know, I’m new to most of this.
Hi,
This is an old comment but I scrolled through this post and saw that no one responded. I also see a lot of people post this. So here's my take on the topic.
Let me first rule out the obvious. It all depends on what kind of fish you have. I have a bunch of different types of fish, including puffers. They are straight omnivores and only get frozen and live food. Their entire diet consists of blood worms, snails,
mysis shrimp, and brine shrimp. They are extremely healthy as they only require meaty foods.
My
danios and
tetras on the other hand have different dietary requirements. They're omnivores and need to follow that diet. Flakes and pellets (from a high quality brand, not one that uses lots of meal products) are great because they include meat, algae, kelp, veggies, and other
vitamins/minerals added directly. It's a rounded diet in one can. If you feed them multiple kinds of dry food like
Bug Bites,
NLS pellets,
Omega One, and a Spurilina based pellet/flake, they'll be even healthier! So it's recomended you use a few types of dry food that have different ingredients and give them frozen food a couple times a week.
The frozen food itself isn't bad, it's actually very healthy, especially for carnivores. It just doesn't include all the nutrients your fish need to be properly nourished.
Most omnivorous fish we keep as pets eat bugs, small crustaceans, worms, and algae, so it's good to ensure their diet consists of all of that.
