unfortunately, in this hobby, LFS's seem to not always be the best people to trust.
And I understand why completely, it's just business not personal.
If you go into ANY other store and buy something, it's on YOU to know what you're doing.
If you buy an iPhone, or a Table Saw, you're the one who has to know what to do with it.
The same applies to Fish stores, You wouldn't buy a table saw if you were afraid you didn't know how to use it and were going to injure yourself.
In the future, don't buy fish or inverts if you're not confident you're not going to hurt it, and I promise you, you will do just fine in this hobby.
anytime you feel someone is making you feel dumb or stupid.
Just realize to expierinced hobbyist, it's like you telling a carpenter you bought a table saw and cut your thumb off, most likey they're going to haze you a little.
