Tridacnid Clams: The Basics
By Elizabeth M. Lukan 7/22/99
Tridacnids in the home aquarium may spawn after some kind of disturbance to their environment. This would include excessive additions of freshwater, increased lighting, addition of carbon, or UV exposure. The clams sometimes die a few days after spawning in the home aquarium. This is probably because of the disturbance to their environment and not the actual spawning. But, there is also the chance that the sperm release may be toxic and the amount of sperm within the closed system of the aquarium kills the clams. In the case of a spawning in the home aquarium, a partial water change afterwards is recommended.
