We got 2 Panda Cories and 1 Black Phantom Tetra two weeks ago - all were living comfortably in the QT
. Yesterday, since everyone looked good (except for one of the cories having a bit of a clamped fin and being a bit quieter than usual), we decided to move the three into their permanent home (10 gal
with 5 Neon Tetras, 1 Black Phantom, 1 Panda Cory). We did not acclimatize them because the original QT
water was taken from this tank, along with the daily 25% change water as well. The QT
was also 'insta-cycled' by taking the extra sponge out of the 10 gal
tank and putting it in the QT
So after a relatively painless netting, all of the fish go into the 10 gal
, but the cory I mentioned earlier is decidedly unhappy. He's settled right up against a piece of driftwood, not moving, breathing heavily and has turned a dark grey colour.
This morning, I turned the tank light on expecting a dead cory, and see that he's moving around a little, but travelling kind of like a football - spinning around as he swims and very erratic.
So my questions are:
(1) What's going on?
(2) What do I do?!? I'm afraid that trying to net him again to put him back in the QT
will be too stressful for him...
I found this thread that seemed to have a similar problem, but no solution... http://www.aquariumadvice.com/viewtopic.php?t=18088
