• Fry Care: Feed newly hatched fry with finely crushed high-protein foods; maintain excellent water quality

📝 Care Summary

By maintaining optimal water conditions, providing a suitable diet, and ensuring a well-structured environment with ample hiding spots, the Gold Nugget Pleco can thrive in home aquariums.
