Thanks everyone! It actually looks really good I think It's better than a background or just boring black... I plan on taking it out once my 2nd powerhead gets here... I have lot of surface agitation and what not it's more of just a looks thing... and now the crabs love it so I think they might be mad if I took it away and it wasn't hurting them! Thanks for the advice though I'll definately remove it once the powerhead gets here and find something else pretty to put along the back... more rock I guess...
