Chromis question

[sbauer86]

Is it natural for my green chromis to rapidly shake back and forth? They do it occasionally and I just found one dead in my sick tank.

My Chromis have never done that, the will fight each other to the death.

ive heard that 2 chromis will fight but mine didnt...i think they had some mental disease lol

[marinelife]

It is possible they do have something wrong with them.

sometimes it can be a mating ritual, but if a death occurred i would lean toward disease. are the parameters ok in the sick tank?

[marinelife]

Mating good idea, Are they dong this against a rock/side of the tank?

[jeremyreef]

i used to have 2 green chromis' that would shake and rub up against each other attempting to spawn.

they were doing it out it the open but this morning they were both dead. last week the parameters were perfect, i'll check today and let you know. All inverts seem to be fine, those were the only fish.
