it's not egg. quoting fatherree". I say sperm and eggs because fully mature tridacnids are both male and female at the same time, which means they are simultaneous hermaphrodites. Thus, they can make both and spawn both in the same event. They have to be fully mature to spawn both though, as tridacnids develop testes first with quite some time passing before they develop ovaries. So, sub-mature clams may spawn, but release only sperm."
maybe a half million sperm. he goes on to say
"So, they do spawn in aquaria from time to time, but this can lead to serious trouble in the closed confines on a tank if you don't take immediate action. In fact, if the gametes aren't cleaned up quickly, there's a chance that a spawning event can lead to the death of everything in the tank!"
Later"he problem is that they'll all die in an aquarium and basically rot. They'll do it quickly, at that.
The gametes will start to die in about an hour, if not sooner, and because they all die and begin to decay relatively simultaneously, they can potentially cause oxygen levels in a tank to drop so low that all the fishes and other tank inhabitants may drop dead within a couple of hours. If eggs are released along with sperm and some of them are fertilized, they'll die too, due to the over abundance of sperm. In the wild, the gametes are immediately diluted into millions of gallons of seawater, but this obviously isn't going to happen in an aquarium. The problem is that when too many sperm try to fertilize a single egg, it kills that egg (it's called polyspermy). The precipitous drop in oxygen levels, when the gametes decay can also cause a spike in ammonia and nutrient concentrations, as well. That's bad too, as too much ammonia can also kill everything in an aquarium, and increased nutrient levels invariably lead to outbreaks of unwanted algae. Obviously, there's nothing good about any of that."
clean out the tank!!!!! before you lose it!!!!
