My oscars have just started laying on a large flat rock, do i leave them in there or do i take them out sice they are in a tank with smaller oscars ive already rehomed the syno since he was getting a rather rough time by the 2 oscars when he got 2 close. And also how do i tell if they are both females, one is laying, but can i tell from there bits, long egg tubey thing female and the other just has a short white lump?
