P. magdalenae doesn't eat

  • We are currently upgrading MFK. thanks! -neo
Most of the retics are actually orbignyi

No.

The hobby has always used reticulatus about the ray we see in your papers as magdalenae. You can take a look around this forum if you want to see for yourself.

The same thing can be said about fx. the fish we know in the hobby as scobina. Its actually from Rio Tocantins (holotype collected near Cametá) while the fish we see on the forums listed as scobina, is caught in the xingu (IBAMA has released pics of the real scobina).

And the list goes on...

Best thing is to just ignore it. :)
 
Theyre very small ranging between 2.5 and 4 inches. the 2 larger resemble each other and same with the 2 smaller. I mean pattern wise. i beleive their patterns will change greatly as they age as with a lot of other species.

Nice specimens, although I think these are very different than mine. I think these are P. orbignyi. You can't see the tail on my video, but it has quite long tail, also with different shape. Your's have much shorter tail, mine also has a litle "feather" near the tip of the tail. I'll try to shot some picture or videos so that you can see what I mean.

Does these guys have litle spines between the tailbase and the sting?
