Food Question

I have a few pounds of food left from a Tropheus tank. I was wondering if the food was compatible for saltwater fish. Here is the list of ingredients is there anything that shouldn’t be feed to my new tank. So far all that is in it fish wise is a yellow Tang and 2 clown fish. Haven’t made a plan yet for what to add I want to make sure I can get it all moved and set up first with minimal loss.
Ingredients: salmon meal, soy flour, wheat flour, oat flour, corn gluten meal, dried spirulina algea, shrimp meal, dried plankton, brewers dried yeast, soy oil, lecithin, vitamin supplements a, d3, b12, biotin, natural coloring, ascorbic acid (source of vitamin c). Dried bacillus subtilis fermentation product, dried bacillus licheniformis fermentation

Guaranteed Analysis: crude protein 45.0% min., crude fat 9.0% min., crude fiber 1.6% max., moisture 9.0% max. All natural ingredients, except for some artificial coloring. No preservatives.

My opinion, fish will eat anything and everything. Ingredients in most fish food are mostly the same especially lower end kind and flakes type. Of course there’s specialized ones that are specifically dedicated to herbivore or omnivore.

Of course you want to feed your fish the food of what they would normally eat in nature and that is why some of us will make our own food for the fish from items that are found from the oceans.

To answer your question though. I have and still do sometimes give my freshwater fish food to my saltwater fish with no harms done. Are they getting the nutrients that they are suppose to be getting? well, they are still alive and growing like weed. So, I don’t see why not.

+1 i’ve fed saltwater food to freshies before and vice versa.

Probably should get some seaweed sheets for the tang, my clowns eat basically anything.

Thank You. Its was pretty expensive and Ive got alot left thats why I wanted to use it and not toss I just wasnt sure if the fillers where a big issue. I sent the guy that makes it an email he said it was perfectly fine for both fresh and salt.
