I have a heavily pregnant swordtail, she looks as if she might explode and has squared off nicely, this is the first time i have had a pregnant swordtail the thing is i have her seperated in her own little tank because i want to save as many fry as possible, but 3 days ago she gave birth to 4 tiny miniscule little fry,, i have had platty fry before and they are half the size of these,, she didnt give birth to any more mut is still heavily pregnant,, has anyone had this hapen before? could it be that the "runts" escaped out as they were alot smaller ,, not quite sure what is happening,, any help/advice would be apreciated
