    I recently bought some blue chromis and one by one they seem to be dying. They seem to develop a bruise near their tail fin and then die. Does anyone have any advice what it could be.

    How long has your tank been running?can be high nitrite.the 'bruise' is actually a bacterial infection!

    Have done water changes and water parameters seem fine. If it is a bacterial infection can it infect the other fish and if so how should I treat it. Thanks

    post actual values please.. it will rule out alot of questioning and speculation.. is it not fighting amongst the chromis? i had a scenario whe chromis would pick off the weaker of the lot in the shoal at one stage..

    bacterial infection is another possibility.. do you run np pellets at all?

    Will post actual readings. It could be bullying as they do seem to chase each other and the bruising only appears on another one after one dies.

    can you isolate the effected fish?

    How many do you have and how long has the tank been running? it does sound like it might be territorial but a pic of the effected fish would help alot.

    do any of them look like they are pairing off? any go a different colour?

    How often are they eating .... NOT how often are YOU feeding ..... I mean how often do you SEE them actually EATING .....

    Had a similar experience to Leslie, where the school picks on the weakest fish till it dies. How many do you have and what size is your tank?

    I've also had a couple of schools of chromis over the years that slowly but surely killed off the weakest one until they are happy with their numbers it seems. My most recent endeavour with chromis went from 7 down to 4, and these 4 have been fine for a couple of years now.

    @Viper Looks like you where right. I am down to two and no bruising on either of them.

    I had seven at one stage, two weaker ones got hammered, no we have a good hierarchy.
