I have had Mollies in my tank for months now... a male and a female.
The male is always rubbing himself against the female and it's pretty obvious that they have mated... infact I've seen it.
However, the white mollie female has got a bit chubbier over the past month but nothing is happening. Infact, today she looks slimmer then she has in the past month.
I'm starting to wonder whether or not I have infertile fish as my girlfriends mum's mollies have bred twice in the past 3 months!
Here are some details of my tank if it helps:
The tempreture is usually around 27 degrees celcius
There are quite a lot of places in the tank for the fish to hide
I clean out around 40% of the tank every week or so. (allthough I have been advised by my girlfriends mum that she only cleans her tank once every 2 or 3 weeks and she has had lots of babies!!)
In my tank there are 2 mollies, 4 baby mollies that my girlfriends mum gave me, 6 empire tetras, 6 of the normal tetras, 2 catfish and 2 orange fish. (Not sure what they are as my girlfriend bought them).
Not sure what to do, I really want my Mollies to breed. Any advice?
