A buddy has a 30 gallon with one oscar, he was using it as a grow out and now his 70 gallon is cycled and ready for the transfer. The oscar is around 7 or 8 inches.
He wants to put either a jack dempsey or green texas in the tank with the oscar, we know it has to be around the same size. He plans to get it as a trade in from a LFS, but does he have to put them in at the same time so the oscar doesnt fight with the dempsey/texas when he gets it 2 weeks later?
Should he just leave the oscar in the 30 gallon and wait? I just have a peacock tank so I have no idea.
Thanks
