I was just wondering, of all the brands of spirulina flakes I have looked at, "spirulina" seems to be waaay down the bottom of the list of ingredients...which I have been led to believe, the further down the list the ingredient gets, the less of that is actually in there. Am I right? Anyone know a good brand I could try?
Also, has anyone fed their goldfish Julian Springs Sea Veggies (seaweed I think)

Is it ok to feed to goldfish?
Oh and just 1 more thing...is feeding once a day enough?
Just wondering thats all.
Thanks
