My silver dollars ain't got no tails!

[[email protected]]

I have a 75 gallon tank with: six large silver dollars (4 inches),
four large goramis, three big bala sharks (six inches), two clown
loaches, a few cory cats, assorted tetras, two tiger barbs, and a
plecostamus. (sorry about the spelling). I keep the tank at 78
degrees. It has been set up for a year. No problems or deaths in six
months or so. The fish get along great, very peacefull tank. But I
suspect it's a different situation at night.... All six silver dollars
have little or no fins left! Healthy otherwise, but they look sort of
goofy with no tails. Every other fish has perfect fins. Any ideas?
Also, about a dozen of my fish are in the four to six inch range now.
Does this seem like a crowded tank? I do fourty percent water changes
every Sunday with HARD well-water. Oh, I feed them flake food and
shrimp pellets sparingly. Thanks, Dan

Maybe it's a nutrition problem. Silver Dollars eat pants in the wild. Perhaps
a little cucumber or parsley would serve them well. Or get some cheapo
aquatic plants to tear apart. That last option is a bit high risk. You can't
always tell what's going to hitch a ride on the plants.

Tiger barbs? Those are some of the most notorious fin-nippers in the
hobby. I'd try removing the tiger barbs and see if the silver dollars
don't get better.

Sounds like a crowded tank. I'd remove the tiger barbs as the previous
reader said and get some cheap plant bulbs from WalMart to grow in the
tank so the silver dollar can have something to eat too.

As a lover of Metynnis species (Silver Dollars) I'm sorry to hear of their
condition. That said, I would suspect the Tiger Barbs as Elaine said they
are notorious fin nippers. Remove the barbs and observe the SD's for the
next two weeks to see if there is any fin regeneration. Tea Tree Oil, the
main ingredient found in Melafix can be used very very sparingly to help in
the repair of damaged fins.

When I had Silver Dollars, I used to give them a Spinich Leaf, every day,
stick the stalk in the gravel, and watch them tuck into it.

SD's love all types of leafy vegetation. I fed a variety of food, including
romaine lettuce, etc. Just so you're not mistaking me, the tea tree oil is
not a food but used as a medicinal product. :)
