How can I cure my crayfish?
He has body fungus. It
consists of white cottony fungus around
his body and eyes. It is getting worse.
I have bought medication, but it is not
working. He is housed with a cichlid
that is perfectly fine. He’s been sick for
about a week.
around with it (protection in numbers). It
worked well. They are inseparable. And I
have a Jack Dempsey, about 6 inches. They
sold it to me as a Jack Dempsey, but in your
book The Guide to Owning Tropical Fish
(T.F.H. Publications, 2003), it looks like the
ram Mikrogeophagus ramirezi. I have other
names for him, as he is very aggressive! He
killed six fish two years ago when I started
I also have two yellow Pseudotropheus
lombardoi, I think. They are bright yellow
with black fins, both about 5 inches long.
Many crayfish are often carriers
of pathogenic (disease-causing)
fungus, but they are resistant
to it themselves. That is, they
normally show no symptoms. I hate to be
the one to tell you that treatment is difficult
in infected individuals that show symptoms,
and the infection is normally fatal. The good
news is that most crayfish are resistant to the
disease, so you shouldn’t have problems with
I have one pleco, brown with black spots,
about 9 inches long. Since I added the
second oscar, all the fish do well together.
They have all been together for two years.
The oscars keep the peace, and they are all
in a 55-gallon tank. I want to get a 250-
gallon tank sometime in the near future. I
know the oscars are supposed to have 80

I just wanted to know what
plants I should put in my fish
tank. I have fake plants right
now, but I would like real ones. Plus, it’s
better for my fish, right?
I have two red oscars. One is about 10
inches and the other is about 12 inches,
both female. I know this because they both
lay eggs a lot. And they eat them because
there is no male, I think. They almost
always stay together.
There are several issues here.
First, do fish do better with
plants? That is not always the
case, and some of the fish you
have are likely to uproot the plants if they don’t
shred them outright. I’m not sure what species
of pleco that you have, but it could very well be
herbivorous. Most of those species eat algae,
but they aren’t opposed to an occasional plant
salad. And some of the cichlids uproot plants
as a result of their aggression, something that
is technically called “displacement behavior.”
The other fish ate the fins off the first oscar
the night I put it in the tank, so the next day
I went and bought the second one, to pal
I’m not sure what the aggressive cichlid is
that you have, but it most assuredly is not
