This fish is still large but hasn't dropped any fry at all, however some other mollies which I got a few weeks later have had their first fry on friday just as I got back from holiday, I have home the fry in a 30ltr tank and all nine that I recovered from the main tank are doing well so far.
One suprising thing is that this molly is now mostly black with only a few small white areas, I hadn't realised this until recently going though my pictures.
I think I will need to rehome my single male Molly as I am concerned that rehomeing regular births of molly fry will be problematic, and quite a few will survive each month due to my java ferns and java moss which are both quite dense now.
