For the last few months I've been planning a P. Saulosi species only tank, but sadly will not be able to purchase them because of a crisis in my family that nearly sucked up all my funds. While the Saulosi aren't exactly expensive fish, with shipping they end up being way out of my price range. So I'm here to ask about what you all would recommend for my tank instead. I'm looking for a species or for several species that are more common so that I can find them locally. My tank's water is extremely hard and the pH is around 8.2 with no fluctuations. The temperature stays around 78, and I have over 120 gallons worth of filtration and lots of rock work. Thanks in advance for your recommendations.
