Hi mfk! Well as said in the title frontosa with rays (motoro) I'm half way through building a 8x4x2.5 and well Im really liking the frontosa but as I plan on adding rays soon I don't want to lose one due to unsuitable fish for them they will be with some pbass Oscar and tinfoil barbs and a silver arowana but well do frontosa do well with rays has thus been done is it a hit or miss situation? Or will work fine? Cheerz
