I guess for me it's when I started, I had no idea what anything was in a tank and the lfs I found in the beginning was absolutely no help whatsoever. I got my live rock there and it was full of bristle worms. And when I say full, see pics attached. I think the leader escaped and is living in my wall to this day. So I got some pieces out of their frag tank I now know were dying and all had a hitchhiker aiptasia attached. Needless to say before I knew what they were I had at least a thousand aiptasia and could not get rid of them. So what corals I had that were not brown and already removed from my tank were a few zoa and a xenia that sorta were alive. They would not grow because no one ever told me about testing, let alone dosing. That was for hard corals they said, which they did not carry and I now know why, because they have no clue how to care for them. I had to take out the fish and start a whole new tank. I would have just gave up if I had not found the store I use today. I guess in a way, the first shop was responsible for me finding all my friends I hang out with now on a daily basis. So for that I'm thankful but still wasted a ton of money. And if anyone ever tries to say these pics are mine, I'll deny it!!!
