Okay so I have a 90 gallon tank with a male and female marbled molly. For a few days I noticed spawning behaviors and my molly got very fat in the next period of time. I have no other male female pairs of the same species in the tank yet there is a single molly fry in the tank. I see no others and my molly still looks like she has quite some weight. I have her in a box in case there is more. Any other opinions on what the next sequence of actions I should take. Please Help!!
