My dad has a 75 gallon tank with two jack dempseys and one tiger Oscar. The tiger Oscar is about four inches, one of the dempseys is two inches, and the other dempsey is about three and a half inches. I saw this earlier today and it was much smaller ( it probably doubled in size in 8 hours.)There was only one of the black things when I left for. school and now there's four Can it be eggs ? It seems like the tiger Oscar is trying to defend it also it's been hovering over it all day.
