Mach, I will bet that 25% seawater will be a very bad choice for cyanodorsalis!
When I first got these fish from Charlels Nishahara (sorry about the spelling)
some 8 + years ago they didn't live for very long at all. He had us putting
them in something less than 1/2 seawater (4 Tablespoons/gal) and then
alternating with lower concentrations. They didn't last very long at all.
Same happened with the second batch also kept at low concentrations. I will
bet that for long term happiness of the fish you are going to need higher
concentrations. I think I remember that you were currently keeping them at 50%
seawater? How many eggs are you getting per week, 50 or more per 6 fish? If
you are only getting a few then they are already hurting. Are you going to try
and mix them with your Ross River signifers? If you could keep them from
beating on each other that would be a good display. Has anyone kept the
cyanodorsalis in 100% seawater? That might be an easier way to go to find some
macro algae that will grow with them. Some of that is supposed to be fairly
easy to grow, haven't tried it though.
