Tangs f/s

Is that sailfin a regular one or a desjardini?

 

This one is the standard sailfin

The spots on the fins is what is the biggest difference in the adult phase, I'm not sure what a standard juvenile sailfin tang looks like

 

Look at the picture from LA of the juvenile desjardini again. Focus on the top fin. Notice that it has a pattern of yellow and dark stripes (when flared open) that continue the body stripe pattern. Also notice the body pattern is wide white and thin dark vertical stripes. Do you notice this pattern on yours? If so - dibs.

 

Yes that is true (look at the links I posted) but his is possibly a juvenile desjardini, which LA shows in an inset pic. The spots don't show up until later but there are other traits that indicate it is desjardini and not standard. Another trait appears of the juvenile appears to be a clear tail fin

 

Here is the standard sailfin






Here is the Desjardini Sailfin with juvenile insert





On Desjardini Juvenile:


Clear tain


Yellow anal fin


Stripes on top fin


Vertical banding is wide white with thin black (may not look like this exactly)


EDIT: Desjardini Sailfins also appear to have more of a black/white stark contrast. Standard ones are more brown & yellow. But if stressed the Desjardini will turn really, really dark, like black.

 

Look at post #7 here

Does he look like the 2nd pic?

 

Ok, if it has the wider brown stripes with thin yellow stripes running through the brown, then it's definitely a standard (pacific) sailfin
