Raising Stiphodon fry; help needed

[Muis]

Today I noticed small fry in my tank only occupied by Stiphodon rutilaureus
Since the tank has been split up in two territories I was not really surprised but still very happy. Until I realized that really little is known about raising these critters, rumour has it that the fry migrate to the sea to grow up and return in an adult stage.
Question 1: the migration of the fry, is that really sure, or has it been an assumption?
If true than question 2: in what time frame should reserve for the "run to the ocean": when should I start to add salt and in what speed?
Question 3: any other advice is really welcome!!!!
Grtz,
Rob

Are you sure they're Stiphodon fry? Is there anything else in the tank?
I wish I could tell you how to raise the fry. To my knowledge, it's never been done successfully. Are they still alive? Maybe you could separate the fry into two groups, keeping one in fresh and then try to move the other to saltwater over the course of maybe a week.

I did just that but I terminated that experiment because after five days 50 % of the fresh water group had died and the survivors were also 30 % smaller than the brackish water animals.
And Yes, I am positive hat they are Stiphodons, they match even the types of gobies as described in the thesis of Kim Bell.

That's very interesting. But, the brackish group is still alive and well? It would be great if you bred them. Are you raising the SG or did you just kind of acclimate them to one salinity?
Good luck.
