If you do things like regularly change the oil and such, you can not only
expect a long life out of your car, but your car will pollute less as well.
Glad to hear you keep it in tune.  A badly tuned car pollutes much worse
than one in good tune/condition.

The name-calling is in jest, right?

Not necessarily significant.

Just how polluting is a modern car?  Just how much of a difference *is*
"several times"?

No, but the pollution produced in the manufacture of a new automobile may
compensate for the amount of emissions produced by his current car.

It's a real shame that the pre-catalyst cars can't be safely retrofitted
with catalytic converters (certainly not without *major* expense) due to
the heat shielding problems.

>You're part of the problem, not part of the solution.  

Well, be fair.  *Anyone* who drives a car, rides a bus, draws electricity
from the local coal-burner, uses a gas stove, or otherwise causes more
pollution-producing activity to occur is "part of the problem".

So just where do *you* stand in all this?  Or is the word "hypocrite"
highly applicable to you, as I strongly suspect it is?

>I am not an official Oracle spokesman.  I speak for myself and no one else.

No doubt the Usenet Oracle would be annoyed if you claimed to speak for
him/her/it.  Fortunately for you, you don't make any such claim, so you

	Good point.  I get to become good friend with the owner and workers
of this one store and they know exactly what I have in my tank and what
I am looking for.  Since I am a T. clam nut, they always tell me when
they expect the next shipment (which is becoming vary vary rare now).
It is also helpful to have one of them come to my house and check on
my tank and do water change every other week when I am out of town for
a vary good price, non of that $50 to show up and $50 an hour stuff.

Ed, you missed the point of that remark.  Whoever does the unit conversions
at AFM does not bother to think about the applicable standard sizes and 
measurement precisions.  When an author says "a 5 gal volume", translating it
into "18.93 liters" is a misuse of a conversion key on your editors' 
calculators.  A 5 gal American tank is roughly approximated by a 20 l 
European tank.  

It gets even worse when the author gives a numner of ounces per gallon
and your edotors blindly convert it to gram per liter, but do not bother to
normalize the units: 20 oz per gal is NOT "566.99 grams per 3.785 liters",
it's not even 149.78 g/l.  Given the 1 significant digit precision of the 
author's measurement, the proper conversion would be 150 g/l. 

If the conversions are done to benefit your readers in metric system 
countries who are incapable of using a calculator and a conversion table
(which you can prvide for them somewhere in the magazine), why trust them 
with something as complex as rounding up to the nearest "standard" 
measurement?

Could this be because of your marketing techniques which place AFM on the
counter in every pet shop along side with Cat Fancy, Dog Fancy and Bird Talk
because your magazines cary practically no ads other than from the major 
manufacturers and no mail order house ads?  

Oh, and did I mention my perennial peeve with your magazine: the colourful
photos which have nothing to do with the articles and trite, inane captions?
Well, I am doing it now.

Actually 3 of my fish had the exact same symptoms.  I talked to quite a

fungus medication.  When that didn't work I didn't know where to turn.
All 3 fish were female swordfish.  They all recently had been in a
floating breeder in the tank (within the last month).  Finally after 2
died (they got worst - a curving of the spine, a really excessive
attempt at breathing, and an inability to keep swimming balance).  The
last one was headed the same route so I very carefully put the fish in a
net and examined it.  Much to my surprise she had "strings" of stuff
wrapped around her - after carefully removing them by gently rubbing her
with a wet finger - I realized what it was.  Cat hair.  I have a long
haired cat who loves sitting on top of our mantle watching the fish.  We
have a glass top with a "gap" due to pressure and also when we opened
the top to feed little pieces of cat hair were going in the water.  The
affected fish were literally "trapped" in the breeder at the top of the
water with the hair falling on them for a week at a time usually.  After
I took off the cat hair and put some liquid on her to refresh her slime
she recovered fully (it took about a month).  Ever since we wipe down
the top of the aquarium every time we open it, the cat stays on the
floor!

Summary: How much weight can a floor take


I'm wondering if anyone has any information about the weights that floors are
made to take safely. I'd like to set up a (what I call) large tank, but I live
on the fourth floor of an old apartment building. I'll give you some details,
and maybe someone can either help me, or direct me to someone/something that
can. 

Proposed tanks:
33gal with 1/4" glass
or
45gal with 1/2" glass

Stand:
Steel, custom made, open stand (not made yet, a friend has one, made to
withstand 800lbs, lifetime garantee)

Apartment:
fourth floor (top floor)
1930's apartment building in upper class area
in good condition, original hardwood floors
the tank will be going in the living room, which has an ajoining dining room


There is nothing really heavy in the living room yet, a 10gal aquarium, TV,
stand, futon, bookshelf, etc. There are a couple of reasons I'm a little
worried. A friend of mine recently set up her 33gal in the living room of her
old house (same area). The floor was NOT level when she set it up (higher at
one end by about an inch), but now it is. Second concern, there is quite a
noticeble sag in the floor in one of the bedrooms in my apt. 

I'm wondering if the weight of this tank is just too much for my old floors,
or do I have some leeway? What's the weight of water per gallon anyways?
I know my bathtub must be about 50gal, but that's not permanent, and it may be
bolstered underneath. 


Please reply by email, or by posting if it's general interest.

Years ago I kept a 30 gallon aquarium. I had an eel that was about 6 inches
long, silvery brown. It was very narrow, almost ribbon shaped. It had a very
sharp nose. It had a tendency to stick its nose into the gravel, and then
with a huge push would burrow down into the gravel. It would later emerge with 
little more than its head poking out of the gravel.


Here's my question: what would an eel like this eat ? I tried putting baby
guppies and other fish in the tank, but none of them every disappeared.
This fish lived for about a year, long after I tried providing it wish fish
it could eat, until a friend who was caring for it lost it in the sink
(I'm still not sure I understand how).

Can someone explain this (to me long standing) mystery ?

Help! My angel that is four years old has all of a sudden ended up upside

bacteria in case a secondary infection sets in on the tank.  The fish eats 
and if you go near the tank it rights itself and comes to visit.  It's 
breathing appears normal, and I think it may have improved a little today.  
Has any one every heard of such? If it was swim bladder disease, how do they

About 2 or 3 days. Oddly enough, I just had an angelfish lay eggs
last Saturday. I suspect they are hatching as I write. I was just
reading up on breeding angelfish last night. You probably don't
need to remove the parents, they usually look after the fry.
In my case, the male was being a bit harried by the female so I
removed him to another tank temporarily.

>  2. What do I feed the fries? Should I remove them from the 55 gal(fries)

After the yolk sac is consumed you can feed them freshly hatched brine
shrimp. You can also use boiled egg yolk that's been squeezed through
cloth or some sort of sieve. Maybe some yeast would also work. Start
the brine shrimp hatchery now.

>  3. Any reason why some of the eggs were missing? I'm assuming the following:

The parent crush the eggs that are bad or fungussed. I assume there are
no other fish in the tank. If there are, they could be eating them.
Although the eggs are sticky, some could fall, especially if the
powerhead vibrates.

I don't know the answer to that one.

I'm not sure what your saying to me here. 5ppm is pretty high. I
believe Moe recommends <1ppm. I switched from Stress Coat to Novaqua
about 2 months ago because that's what the store had. Within 3 weeks I
started growing hair algae like there was no tomorrow. Switching to
Amquel and repeated water changes has finally given me some control
and I would never recommend adding phosphates for any reason in any
concentration. Stress coat does not have phosphates in it. I can mix a
batch and test and no concentration is evident. As for detoxifying
heavy metals; I've never had a heavy metal problem as far as I know so
this is of no interest to me. How do you test for heavy metals anyhow?

I would sit back, relax, and prepare to watch the parents eat their young.
Sad, but sometimes soo true.  The few pairs of cichlids I've kept sometimes go 
thru a learning period re taking care of eggs and young.  If your fish 
are in a community tank with the usual assortment of fish, your chances are
even slimer of success.  

Any good book should be able to answer your questions.  I don't have the 
specifics.  The times I've breed angels, I did so artifically.  Parents were
kept in 20H gallon tanks, with another tank waiting for the slate or leaf
(no powerheads 20 years ago!).  Hatching takes a few days, then a day or three 
before the wigglers start looking for food.

Pay attention to the instructions - your cannister filter *must*
be lower than the water level in your tank, because it depends on the
syphon.  The powerhead in the cannister is actually fairly weak.
If you can, put the cannister filter in your stand.  I hope you
bought quick-release valves.  We discovered very quickly that
they are *very* desireable.  Mind you, I'm a very lazy fishkeeper.
Lazy enough that we no longer have a cannister filter.

I've noticed one of my Angelfish is suddenly acting very strange.  It is
the smallest of 3 (all between 2 - 2 1/2 inches body only) and it has
started "hiding" between two plastic plants that are _very_ close
together.  It "hides" on an angle with its mouth pointing up and
protects this area very diligently.  It is eating normally and before
the last couple of weeks it had 1/3 of a 35 gallon tank for its
territory.  I also have 2 paradise fish ( 1 male, 1 female), 2 newly
acquired snails (still small), various tetras (14 including 5 neons).  I
also have 2 swords.

Any suggestions?
