The female is a conservative 14-15 inches. She is a house. The other female is probably 10 -11 inches and the male is probably 8 or 9? he is very mature as far as claspers go. Very large and very rolled. We will see shortly I hope.
My rays don't touch the fish. Lucky that way. The Hystrix are also small enough that they would have to work pretty hard to take down the SD or the Altums. I still have a few rainbow fish in there and if anything the rays would take those down but seemingly aren't interested in them
