Help! My juvies are acting wierd......

[Timbits]

Hi i have a batch of juvies right now that just finished meta phase and half of them are swimming upside down near the surface of the water...... has anyone ever experience this? i've raised many batches of clownfish before and this is the first time i've seen this...... are they going to be ok? why are they doing this? any help would be appreciated i just hope they will be ok...... thanks

Upside down? That is a bit odd.

How's the aeration in the rearing tank? Is it possible they are ingesting small bubbles causing them to loose equilibrium?

Other than that, I'd take a good luck at water quality, as that is typically the number 1 root problem of larval and juvie rearing.

only half of them are doing this...... the other half are swimming fine . they seem to only do this right at the surface of the water its like they're walking on water but upside down ... are they just playing?
