grow-out tank w/tail rot?

[fishcakes]

We have a 30gal split tank with fry and juvenile cichlids. For the last few weeks the snow white or albino zebra juvs have one by one been resting on the glass bottom like they are paralyzed soon after their tail fin is gone and then they die. Strange thing is is that it is only them. None of the other cichlid fry or juveniles are affected.
So do I treat for tail rot and do more than weekly water changes and filter maintenance? What would you do? Or what do you think is happening?

Do you have any pics of what they look like?

First pic is of one that has lost entire tail. I let him go.
Second and third pic is one that is showing loss. When swimming tail does not move.
Forth is a pic of one that showes just a little.

It looks and sounds like a bacterial infection ...you need to try coppersafe for a week and then metronizole if you want to give them a chance. The coppersafe will kill anything external and the metronizole will kill anything internal..

Also check you water perimeters...you may lose some fry but I would separate the fry and put them in another tank and make sure you clean out any dead fish right away cause they cause bad water...ammonia ......

But why just the albino? None of the others are affected. Some were put in at the same time as them and others as recent as a few days. Could it just be that batch of young that has a prob.

Yeah it could have been that batch that has issues..
