thank you everyone. Mo, i agree the 300 would be too small in long run. but should be good for a year. I have a couple larger tanks but not really friendly for divider set up it is a 540... so maybe i wont need a divider. I am planning a 3-way divider in a 300, male in middle females on ends with powerheads pushing currents over both areas so male can fertilize thru dividers. I am definetely gonna introduce without dividers to see how they take to eachother. ill have dividers ready. ill take a video of introduction
I still think anything is possible and would love to hear more of what everyone thinks.
