PLEASE READ!
So if this just isn't the icing on the cake of an awesome weekend...my Pseudomugil Furcatus have been in the new tank for less than 2 days and the female is releasing eggs! I had no intentions to breed these fish, but I've read up on it now after I saw the eggs, and it seems that it's a real possibility. It's always exciting to see breeding behaviour in your fish because you know they're happy.
I will wait for the tank to grow in and become more established before I attempt to move any eggs to a separate container to hatch. For now I'll just let them do their thing and wait to see what happens!
