I refer to it as high because I am used to my tank being in the 1.09 range or so.
This is far to low for any saltwater livestock to live in full term. This is more along the lines of a temporary treatment known as hyposalinity.
keep the specific gravity of their fish holding tanks low for several reasons (it's cheaper, fish handle it o.k
., may reduce chances of parasites, etc.). It is important as mentioned to not acclimate for a given time period, but rather to acclimate until the specific gravity in your bag (or other holding container) matches that of the display or better yet, quarantine tank.
As a general rule, fish can enter an environment of lower salinity much more easily than entering one much higher. This is because their osmoregulatory system (removes salt from their bodies) is not taxed as much (and why fish at LFS
can go right into the tanks, they are normally lower SG
). A jump of more than .02-.03
immediately or even within a few hours can be quite dangerous. Without knowing what the SG
was after dripping for an hour, one can only assume that the water did not closely match, or something else killed the fish.
