I had a recent experience which I want to share. I introduced a
green spotted puffer into my 45high tank to reduce the pond snail
infestation to manageable proportions. After a few days, I realized that
this was a bad move for the sake of my angelfish, who were losing ventral
fins at an alarming rate. I yanked the puffer, and began to treat my fish
with vita-chem to help them regenerate their fins. I initially avoided
dosing the entire tank, preferring to supplement the food and maximize the
vitamin uptake. I had to leave town for a week, however, and decided to
dose the tank for the week I would be gone, since the fish wouldn't be
Now for the APD-relevant part. Many of the older leaves on my marble
queen sword and much of the valisneria began to act like they had been
burned by a fertilizer. The leaves turned brown and began to decompose.
Fortunately, the plants were really healthy (in this tank at least :->)
and are in no danger of dying completely. The fish are ok as well.
Anyone have any similar experiences?
