It seems as if P. hepatus is now happy and feels safe. For the first time she is swimming around with the other fish. Cool!
I have been running the RO unit since two days ago trying to make enough RO water for a 60l water change. This is taking forever!
I bought some Nori from Woolies and attached it with the SeaVeggies clamp. After about 10 minutes the Purple Tang started nipping at it - and now every now and again it eats some. The Yellow Tang does not look as much interested, however it did eat a couple of pieces that came off.
