Hey everyone, I know that wild red devils develop their lips from going after inverts in rock. If I was to use lava rock in my aquarium will it make their lips develop? I know it may sound like a silly question but I just gotta know.


Thanks guys, I am going to make sure that they are true rds. @Reaper13- I heard that captive bred rds don't develop the lips, that's why I was asking. I've had what I thought were red devils before but never got the lips, so I always wondered.
