"Pretty Tetras"

actually they are my friends fish.....i would have to stop out tomorrw to take a pic....the tank has 2 tetras...and 5 differnt goldfish...so the tank is definately not overstocked...its 20 gallons
 
she has had them for months now...and they seemed to be fine in that temperature....
 
I would say ICH is right...actually....what could she do to help her fish back to health ???
 
No, there actually is a fish called a pretty tetra (also known as a Garnet Tetra).

The tetras probably have ICH, and to help treat ICH, then you could try raising the temperature gradually.
 
that is the only way for her to help them ??? what about what the girl said...about shoudlnt keep them in with goldfish ???
 
Your friend is exceedingly overstocked. One goldfish won't do well in a 20 gallon, let alone 5 plus tetras. "But they're only feeder goldfish...." Feeder goldfish can get 12+ inches and should when they are kept humanely. If you need a more in-depth try a species profile here at AC. Print it out, take it to your friend.

As for keeping tetras with goldfish, in an environment too-warm goldfish will become more susceptible to diseases. Conversely, in a too-cold environment tetras will become more susceptible. The two fish aren't meant to be together.
 
Basically the tank should be treated for ich as soon as possible and then your friend should make a decision. Either take the goldfish back and keep a small tropical community. Or, take back all the fish except one goldfish. Then be prepared to get a larger tank in the very near future. Otherwise I'm afraid the tank just won't work in the long term and will be one big hassle.
 
so the only way to treat ich is to gradually warm up the tank...is that what I am being told ?
