.Inactive during light hours. Very active hunter after dark
I just wanted to add that my experience of these species is very different to this.
Both species "sleep". The salivator lie on the moss after lights out, and are still there when I turn the lights on before the sun rises.
The borneensis (male at least) has a strict regime that I can set my watch by! The male, at 9:30, will go to his chosen log in the tank, go underneath it, and rest there. Again, when I turn the lights on, he'll still be there. His eyes go that silver colour when he rests as well, as I've seen in the majority of other small puffer species.
As for their activity during the day, the borneensis male is very territorial, and aggresive. The salivator male is similar in activity, very active during the day, but not as territorial.
I'm not saying the pufferpedia is wrong, but from my experience it varys quite greatly.
With regards to breeding of GSP's, in Baensch Aquarium Atlas Volume 1 Baensch states that GSPs have been bred in captivity and describes the care (substrate spawners, male guards the fry). Maybe worth adding for GSP owners?
