Hello Schreiberi,
When I lived in Belize I collected triporcatus from the Belize river and also collected acutum muds. I could never hatch acutums but others have hatched triporcatus... I would think salvini wouldn't differ too much but unfortunately the only advice I got was set up the eggs and place them in the incubator turned off. In time they would hatch... never did... Best to you- Mike S
