Hey guys i had a couple questions first thing i just picked up a baby silver arowana. Well it was sold as a silver but is it normal for them to have a blue tint to them and a good amout of blue on there front fins and a blue spot behind his head. This is my 2nd one and my first one did not have this. Also a lfs is selling baby black arowanas with the egg sack still attached but about to fall of for $20 is this a good deal? Thanks for the help in advance
