Looks good so far......With more lr,you'll be set......Just please don't add an anemone,as most newbies do.......But,as I stated earlier,looks good so far......
I can't id the thing you were asking about.....Maybe someone else can....
As much as I would like to add a anome I am not going too, just for the fact that I hear that can live in the wild for a VERY long time and I also know that the sucess rate is low so no I wont attempt it. I am nervouse about adding a fish, so if that tells you anything.
