Thank you so much! I really appreciate it! Ill look into the area they're taken from more and get back with the salinityYes. I have a chart ill look for and attach. It sounds like you could treat them like green spotted puffers. I'd say do 1.022 Which is just cheap instant ocean mix..
I have no idea what's their naturally salinity so I'm just guessing.
Most def skimmer with messy puffer(s). It would cut back on water changes. You will need ro or rodi water.
