Hmmmm, I dunno, is it ok with Captain America if we carry on discussing the original topic? Hopefully that was the last of his emotional outbursts for a while. lol
So back on topic …..

Sera has been around forever, IMO is very similar to Tetra, both German companies that use some rather questionable lower quality raw ingredients, while stacking the terrestrial based plant matter. As an example, in this formula the 2nd, 3rd, and 4th ingredients listed by dry weight is WHEAT. Add all 3 ingredients up, and wheat would more than likely become the main ingredient listed on a dry matter basis. Not cool, especially for a fish that is a carnivore. Ingredient splitting is an old trick going back several decades, and as much as I love German technology, when you look closely at their fish foods they are all typically designed in this manner. Tropical brand is another brand that IMO is very similar to Tetra, and sera. Their EU ingredient list accountability is sketchy at best, and raw ingredients such as "cereals" don't pass the sniff test.
So in this formula, instead of using things like Calcium caseinate, to boost the protein levels in this formula, how about adding more fish meal, moving the green lipped mussels to the second ingredient, and losing the wheat germ and wheat gluten completely. In their place, and at a reduced inclusion rate, add some aquatic plant matter, some various algae, even a dash of spirulina would be nice.
And Matthew, unless you are feeding some rather high energy, cold water species of fish, in a massive system where they can burn these high energy calories off, 14% min crude fat content, which means the typical analysis would be more like 16%, or higher, is not a good idea. Not good at all. Sturgeon require higher fat content, much like a rainbow trout or salmon, which I am guess you are not keeping. Warm water species, even the high energy species, should max out at the 10% mark. Even that is pushing it, especially if one overfeeds.
I'm assuming that you were introduced to this food while working at Pisces? The owners father, Peter, originally brought this food in several decades ago. I think he had an almost exclusive deal with sera at the time, they are one of the few stores in AB that carry it. At least they used to be. Just like all store owners, including Cory, they market, and sell, whatever pays the bills. If they get a better deal on food xyz, and it sells for them, that's what they push. Nothing personal, it's just business.
