Just went downstairs…all but one offspring in Spawn #20 is dead on the bottom.  !#%!#!!@!!

Water test shows completely off the wall parameters…eg. Nitrite at 5 PPM, Ammonia at 0.5 ppm, Nitrate at 40 ppm?!.  Now, whether that’s all the dead fish in the tank, or if that’s the cause, I’m not sure, but I’m thinking cause vs. effect…this must have snuck up on me this week and must have built up rather suddenly.

Since this type of loss has happened so many times now at this stage, I’m admittedly baffled because water quality hasn’t been a problem in prior losses, and yet they all have occurred around this same timeline, so I must be doing something horribly wrong, and water changes should have been keeping this under control (remember, this group got a near 100% water change earlier this week!).  Only 5 days to go from perfect parameter new water to the above?  I’m shocked.  The bioload and feedings simply don’t add up. I’d say I was overfeeding, but I can’t see how that’s the case.  In the past, at this point in time, I’ve normally put the fish onto the system only to watch them all die immediately after.

Looks like I must reevaluate my methods yet again.  Talk about frustrating.

Update – so I’ve been sitting her mulling this over, and here’s the things I recently did – #1 Fed them Brine Nauplii last night.  That seems to be a recurrent theme…feed the babies brine nauplii, have dead babies… #2. I did top off last night.  Is my RO/DI water contaminated? Time to test it…

2 AM Thanksgiving morning and I’m closing out the fishroom.  All but 2 of the babies from Spawn #15 are dead on the bottom of the 10 gallon tank.  No warning, only hours earlier everything was fine.  I moved the two still alive (one white stripe, one lightning) to an empty tank on the larviculture system.  Since there is no pathway in for pathogens, it could only be something related to water chemistry or the introduction of food; the ammonia alert badge remains showing that everything is just fine.  No rhyme or reason.  Hoping the other two a) make it and b) aren’t going to introduce some pathogen into the larviculture system (I really don’t think they are, but you never know).  Could be that something like Vibrio just cropped up and whacked the tank…no clue.
