Ok, so I visited a lfs, that I had just discovered today and was asking the owner about Coraline as I want to start seeing some Purple in my tank
. And he was telling me its bad as it "chokes" the lr. I was like whoa ok... Now he seemed to very knowledgeable but his fish were atrocious he had a mandarin that was so thin, IT WAS IN A BAREBOTTOM TANK!!!! but thats another story. So is Coraline bad?
