I am new to this forum and I wanted to ask a couple of questions. I just bought some Mixed Fruit Tetras. I can't find any info on them on in the net and I was wondering how big do they get, how hard is it to breed them, and how do you tell the males and the females? I also have to Dinosaur eels in a different tank. I was told by the store they are peaceful but they are so aggresive that they killed my shark that was double their size. They also jump out of the water when they see me to try to attack me. Does anyone have any info on them too? Thanks.
