TROPLIST: bouyant trops

[gthomsen@notes.cc.sunysb.edu]

Greetings All,

I have a bunch of trops that have in the last week bloated up and are 
floating semi-submerged (a few even inverted) at the top of the tanks. 
They don't appear to be overtly sick - no sign of redleg.  Anybody 
encounter this?  Any ideas what might be happening and how to solve this? 
My guess is bacterial gassiness, but....???  I have several 20 gallon 
tanks with recirculating back filters, and have been maintaining a ph of 
7.5 with some bicarbonate and a few grams of instant ocean for more than a 
year (so i doubt it's a 'baking soda' effect!  but who knows??) . 

all comments appreciated!

cheers,
jerry
