I just recently got 10 P. saulosi and have been feeding them NLS 1mm pellets which they devour very quickly. I was wondering should I also offer a more spirulina based flake as well? Or are they good just with the NLS. Also I fear since the saulosi eat the NLS so fast that the S. lucipinnis that are also in the tank are getting next to nothing. Any ideas or am I just over concerned?
