They seem to be OK, however there is a generous portion of crushed coral in
the tank to boost the hardness, buffering and pH. I do think that they
fairly susceptable to radical changes in pH, rather than changes in
salinity as I can usually aclimatize these fish down to 1 tsp salt per
gallon over the course of one afternoon. I have noticed that the eggs seem
to be more willing to hatch in water with less salinity.

Got a question for Dave Wilson who wrote:

Do you notice there are more fry in the streams during the wet season? I
have noticed that the eggs seem to all most go dormant until there is a
change in water movement or drop in salinity.
