Clownfish suddenly acting very aggressive

[PoonTang]

If your clowns are acting that agressive then they probally have already laid thier eggs. My pair laid thier first batch about 5 days ago and what a change in thier behavior. have a look very closely, the eggs are hard too see.

I can tell when mine have laid eggs or close to it.....they attack my hand when Im cleaning or arranging a coral....the larger one(female) has drew blood from me on occasion....she is nasty.....

Once the clownfish start to breed, they lay eggs every two to three weeks. Or at least mine do. Mine lay their eggs on the rock work right beside their host anemone. They did keep to the small area where they currently lay their eggs for some time before I noticed that they started breeding.
