I've read that it is possible to keep a GSP in a marine tank, salinity of 1.024/1.025. This can only be done if he is an adult.
I've also read that if you keep corals with you GSP it will nip off some chunks of coral..
My question is, are there corals that the GSP will leave alone, or does the GSP get used to the corals and leave them alone? Or is it better that I keep it in water with a lower salinity and just have stones and wood in the tank??
I know there are decorations looking like coral, but they stay fake, just plastic rubbish
