Going to start my FOWLR tank soon, so im trying to get the best color for my fish.
Is feeding pellets (or any dry food) to fish necessary? I have read a lot that states frozen food; Mysis etc, brings out the color of fish.
Since pellets increase phosphate, Why would people feed it at all? other than being cheap ofcourse
I don't know much about bringing out the color. I haven't tried controlled side by side tests, but I'm not having any issues with pellets and flakes.
Feeding dry fish food is not necessary. In fact, fish generally prefer frozen, and especially live foods. That said, as an aquarist pellets do come with many advantages.
1) Despite the fact that fish are more likely to accept frozen (the majority of fish have no trouble accepting dry), Pellets often contain more nutritional value that frozen. It's like feeding your kids veggies instead of candy.
2) The cost is lower. Although frozen can last a while, dry will go farther. (10 pack of hikari is a good deal but still not cheaper than pellets or flakes)
3) Convenience. Dry foods don't take up freezer space and you don't have to head to the freezer every time you want to feed. Also dry foods don't need defrosting and can be fed automatically.
Oh, and as for phosphates. I'm not sure but I think on BRS they said that Frozen have more phospates. Either way, I run a reef and occasionally test for phosphates, but I have yet do have problem. Not in my 75 where I feed frozen, nor in my 15 where I feed dry. In a fowler phosphates are even less important.
