why are deformities in fish so common?
why are deformities in fish so common? I have read several threads on this forum and on others about people having fry in their tanks and how some of them are deformed. I also keep hearing people say they had deformed fish. Also, without even knowing it, I apparently had 2 deformed fish. I had purchased 4 of the same species and at least 2 of the 4 had some deformity? Why is this so common? Is this due to inbreeding or being raised in crowded or too small of environments? Could it be inappropriate diet or water conditions? Is it just normal for so many fish to be deformed and then in the wild, they simply don't make it long?
