ocellaris clownfish shaking?

[david189]

hey everyone, fairly new to the saltwater side of aquariums. I added my second clown today and the one i had in there before he arrived went straight after him and now every time they get close to each other they shake or have seizure like movements. Could someone fill me in on what could be possibly happening. Is this some form of dominance dance or something?

Its normal. Its like a mating thing. One is coverting into a male, which is probably the one shaking/twitching. Big clown is the female, smaller is the male. As long as they aren't chasing eachother around the tank continuously, your okay.

no, they arent chasing each other but i noticed that they both are shaking

woke up this morning and find my clown how i introduced last night was dead.

that's not a good sign, hopefully it doesn't transfer a disease and destroy your whole tank.

The shaking is how they act tough and say "I'm the boss" to each other. Normal to see when new ones are introduced or sometimes even at feeding time.
Clowns are naturally an aggressive fish, so your first one may have killed the new one. If you try it again make sure the new fish is a lot smaller that the current one.
