Can you give me an idea of how big this platy is and what type of platy? Are there any other fish with curved spines or deformities in the tank? Any recent additions to the tank without quarantining? When it was still in the main tank did it ever go out into the open for food or to swim? We may be looking at a little fish that was born with some sort of birth defeat and too weak to thrive, knowing its current size will help us get an idea if its growth is within the normal range.
