Hi. Is anyone successfully keeping Dwarf Neon Rainbows and Bolivian Rams in the same tank? I currently have 6 Praecox Rainbows in a 40 gallon and would love to add Bolivian Rams, but from what I understand, the Bolivian Rams prefer more acidic water and the Rainbows are the opposite. My Ph is 7.4. Any advice from those who have experience keeping both fish would be appreciated. Thank you.
