i have had a spawning pair in the past.my present pair are 2 years old and mated.I have seen the male cleaning the bottom of a small frag bottom in corner where they hang out but the frag plug is moving around and no eggs yet.would it be a good idea to place a tile of some sort in the corner?would this possibly help spawning and if so what kind of tile?and should i stand it on its side?I would like to raise the fry of this pair as they are spectacular
