Pics of the two cat sharks. One looks male and the one I hatched looks female. Waiting for the female to get a little bit bigger and she will join the male. Similar colors on each but the male is darker, not sure if you can tell in the pictures. Both are active at night when they are hungry. I will try and get a pic of both of them together so you can see the color differences. Waiting to add one more female to these two. Still feeding on raw shrimp and LRS nano frenzy. I think the LRS has the best variety that I could possibly ever give them.
