I guess I didn't explain why I'm determining the lowest point, (or hyposlinity), for a shrimp. It's a parasitic concern, and no, not the shrimp...
. I have new fish in a holding tank. Quarantine, isolation, call it what you will...
The "new specimens" have been in quarantine for just over ten days now and the scratching behaviour is beginning to show with two of the fish. The fish
and shrimp were in retail systems also @ 1.019, or very close to that. My system matched on introduction and over a five day period, the level was increased to 1.024. Then the scratching began. Over the next 4 days, the level was again reduced to 1.019.
My q-tank is rather "un-conventional". It's an established system with an array of inverts, live rock etc...I prefer this approach to the "sterile system". I feel fish are more relaxed and inclined to begin feeding in a "natural environment". Some kinda' fish psychology...? I dunno' it has worked well for me.
The diet is well balanced and vitamin/garlic enriched. I'm not hitting the panic button yet, I just want to keep a handle on this before it becomes serious. I have a lot of fish in quarantine at one time. I nomally don't go on "spending spree's" like this but I need to make multiple additions to my 90g in an attempt to distract a beligerant Purple Tang...
Perhaps I'll just leave 'er at 1.019 and patiently wait...
As always, I appreciate the input !
