OK, I haven't yet found the thread I wanted.
However, in a couple of threads I just reread from Sept,
In a thread on frozen brine gut loaded with spirulina,
Hikari Frozen Spirulina Brine Shrimp
Ingredients:
Brine Shrimp, Spirulina, Water, Pyridoxine, Beta Carotene, L-Ascorbyl-2-Polyphosphate (Stabilized Vitamin C), Vitamin B12 Supplement, Riboflavin, Thiamine Mono-Nitrate, Biotin, Choline Chloride, Folic Acid, Pantothenic Acid, Inositol, Niacin.
David commented:
I feel that a very integral part of seahorses diets should be brine shrimp.
Seahorses in aquaria eat too much fat, dead simple, far too much fat, and as they are a slow non active creature this is not good.
Brine shrimp, like the ones spoken about are good for two reasons,
1) they contain vitamins that are not in high proportions, tho I would like to see figures not just names.
2)the use of these zooplankton as a regular part of the diet lessens the overall fat uptake, so its a bit like a health pill, loaded with vitamins, no weight gain.
Later, in the thread his remark was
Mysids are too fat, as far as I know, PE is around 10-12%, hykari a little lower.
That means 10-12% of total foods eaten, is pure fat.
We must not venture too far from mamalian nutrition with teliosts, vitamins work the same, protien and fats work the same, carotenoids work the same etc.
Protien is the building block of life, is responsible for mucular development, and energy, fat, well we need it, but for a healthy life, only in small quantities. 10-12%, huge, very huge.
In another thread on enriching mysis David commented:
Get ahold of some ongrown brine shrimp and gut load these with spiralina, chlorella and some nature rose and feed it 3 or 4 times a week, 4 or 5 each is fine.
I guess you could say that David is a "commercial seahorse" person that does recommend and use them.
