Actually no. The Molly is from the begining, it one of the babies, my mollies had while my tank was first set up. It is currently as big as my spotted grouper and half the size of my chocolate grouper.
The molly has survived every growing pain my tank has had which is why I have kept him, that and it is actually tiger striped and not your typical looking black molly.
If any tank mates dissappear I am expecting my clarki or my fireflash goby to be the first to go, but I keep the groupers happy with silversides for now........
My molly is like the old man in the neighborhood that has been there forever and seen all the changes but everyone ignores.............
