Looks good!!!! I like the open space.I had a nem that looks like yours. Does yours have white stripes around it's mouth? I had to sell mine,it started moving around and stinging everything in it's path.
Yeah the nem does have white stripes and also a blue/green florescent foot and first part of the tentacles!
Lucky in 12 months hes never moved, ive tried to place in a similar position and so far so good
He was sold to me as a rose bubble tip but im not sure hes actually one
