Not really a matter of the question being valid, Jlone was pretty much right.
We basically know its kind of not possible to get O3s from eating fish only unless you are like a paleo Nazi. Sushi don't really count.
its good to supplement with O3s. Ive heard and tried dosages up to 30g a day but I do try to get quality source products such as those that are not farm raised.
Where the product comes from, like all things, is important.
There has been no conclusive data to suggest that fish oil is bad for you.
Yes, there are some unkempt products, hence why you have to get a good grade fish oil.
I have no idea how good Flameout is but I have taken it before without problems.
Smell the fish oil to see if its good and take a small amount, more than likely youll burp, if your burp smells and tastes like death, its probably bad, also to be smart, check the expiration label
