I mounted a ballast on the inside of a sheet metal "bud-box".  One of those
hobbyist boxes for doing electronics projects.  Anyway, I mounted the
ballast on the inside surface of the top.  The box acts as a big heat sink.
The box gets kind of hot, but does a good job of dissipating the heat.  For
a while, I had a small fan blowing on it.  It was perfectly cool at room
temperature.  I took the fan off eventually, since it didn't seem completely
necessary, in my case.  But having a small child might change things.

After recently talking to some people at the water company, I found out they
add phosphates into the water.  Right now I cant remenber the concentration
they add (sorry).  I have seen different products to remove phosphates but
always thought that this was more of a concern for marine tanks.  Should this
be a concern of mine for my 20 gallon community tank?  I have some assorted
tetras, bala sharks, plecos, black molly.  

Has anyone mail ordered from "aquarium world" located in Minnesota?
Did you receive good service from them?  Thanks.

  Snakeheads are a variety of fish that have a body similar in shape 
to a snake.

  They are from the genus Channa and vary in size from 8" (C. orientalis)
to 48" (C. striata). With a number of species in the 12-14" range and
also in the 36" range.

  They all enjoy warm water (80 degree) and are piscivores (fish is their
natural food). But most are willing to accept almost any type of meaty
frozen food as well. Some (C. orientalis - the Green Snakehead) seem to 
even prefer frozen brine shrimp over feeder goldfish.

  They are usually mild mannered fish that will not bother other fish that
will not fit in their mouth (keep in mind, the mouth is large). For example,
I have had a 13" adult male Channa africanus (Brown snakehead) live in a 
65 gallon tank with a pair of Texas Cichlids. The snakehead had his choice
of resting places until the Texas decided to spawn. The snakehead then waited
at one end of the tank (minor fin damage) until the spawning was complete and
the fry had been lost (no special feeding was provided). He then took back 
his favorite resting place which had been the selected spawning site for the 
Texas. The Texas cichlids both had minor fin/scale damage in the process. But
both species got along reasonably well.

  These fish are spawnable in an aquarium as long as it suits their adult
size. As with most cichlids, they become very territorial at breeding time
with a territory equal to about 3 times their body length. (12" Channa 
africanus succesfully spawned in a 48" long tank with 3 other adults herded
in one end) Channa orientalis is a patternal mouthbrooder producing about 
200 fry per spawn in a 30 gallon tank. Channa africanus lays several hundred
large (1/8 inch) floating eggs in a nest at the surface. Channa obscura lays
about 2000 smaller (1/16 inch) eggs in a nest at the surface. Each of these
species provides parental care to the eggs and fry that rivals any cichlid.
The fry grow quickly and are only canabalistic with much smaller fry.

  They are very tolerant of water conditions and produce very little waste
compared to the volume of food that they eat. Frequent water changes will
keep them happy, and they will eventual come to greet you at feeding time.

I saw a black Ghost Fish for the first time the other day and thought it was  
real cool looking, even for 20 bucks. I would like the fish but I'm worried  
about compatability with other fish in the tank. The fishy list follows:

1 Black Skirt Tetra
1 Silver Molly
1 Clown Loach
1 Black Shark
2 Tiger Barbs
2 Dwarf Gouramis
3 Zebra Danios
2 Neon Tetras (Can't keep those guys alive, I've lost four within the first 24  
  hours of being in the tank).

Could the Tiger Barbs be a problem?? Any others?

Hey Everybody,
	I'm having problems with my 55 gallon freshwater tank and I was
wondering if anyone might have some helpful info.
	Here is the problem:
I started the tank with feeder guppies then after a couple of weeks introduced
angel fish. Then a couple of weeks later introduces some head/tail light
tetras. During this time some of the guppies showed white patches within
their bodies but not on their bodies. They were promptly removed.
A week later some of the head/tail light tetras showed these similiar white
patches within their bodies as well as collapsed pectoral fins.
Then a few days later my angel fish ended up with collapsed pectoral fins but
they did not show the white patches.
	If anyone has any idea what this might be and how I could treat it
I would greatly appreciate the help!
Thanks in advance,
	Will Parsons

Thanks for the defense. When I read this response I was taken a bit off guard.
It was NOT illegal for me to capture the darters where I did. Granted, this
is more than likely not the case in many part of the country, but in West
Michigan, darters are very far from being anything in the neighborhood of
endangered; especially the Jonny darter (Etheostoma nigrum). These small fish
literally are teaming in the particular stream where I gathered my samples. And
they have been every time that I have been there. In fact the Jonny Darter is 
one of the most common darters in North America.

Rest assured Oleg that I am indeed taking excellent care of my little darters.
they have a 40 gallon species tank all to themselves, with water simular to 
the stream of which I took them from. Incidently, this is always a good policy.
If you capture a fish from the wild, always put in water simular to the water
from which you capture it; even if it disagrees with the literature. If it
drastically disagrees, them start with water like that of its natural environ-
ment and gradually change it to better conditions. If you go strictly by the 
book the change in water quality may kill the fish.

According to my CVS pharmacist, this would be an illegal act in the state of

I'm glad this works for 'ya, but if I recall correctly, Grainger's does *not*
offer a 120V rated plastic float switch.  I suspect you're using a 12V rated
float switch to switch 120V circuit.  I'm not sure what the consequences may
be of using a 12V switch for a 120V circuit... I think you'll at least shorten
the switch's life-time and perhaps even harm your pump.  (I do know when I
asked some EE geeks around here 'bout using a 12V switch, they definitely
told me to use a relay to actually switch the pump.)  Even with cheap
powerheads, IHMO it's prudent to use a properly rated switch or else wire in a
appropiate relay.

Hmm. Sounds like a 2-3 cm long 5-6mm crustacean of some sort!
Actually, it _might_ be a mantis shrimp. These are buggers that like
to hang around in holes (some crawl around to), and, suddenly, dart
out and skewer the passing fish. And eat it. I had the good luck
of finding all the mantis shrimp in my liverock before they got any
of my fish. The best way to find out is to setup a trap and see what
you catch. Typical traps are some sort of container that has an
inverted lip, with food inside to attract your prey. Terrible

What is it??? Well, One guy made such a thing out of a 2-liter

difficult to see from any direction but from the opening, otherwise
your prey might see it from the side, try to get through the wall, be
thwarted, and decide that this food was unavailable. This brings up
the interesting question of, "but how do I tell if anything is in
there?" which I still can't answer. :/

In response to the query:  should you mix gold severums

wind up bullying my angels.  but i have one female severum

this would only work with a very mellow severum, and my severums

definate need to organize the three newsgroups in a more orderly fashion.  I've
read the articles against this, but I feel that a re-organization would better
serve the readers and users of these newsgroups.  Enough political talk...
	About my setup:  I have a 30 gal.  with a Skilter and UG.  In the 
skilter I have a bag of Bio-chem beads as well as a Chemi-pure.  I have 2 24"
actinic-day lights over the tank.  Inside there are 4 anemones plus quite a bit
of live-rock.  As for fish, I have 1 skunk clown, 1 skunk pseudo, 2 dominoes,   1 yellow clown goby, and 1 yellow-tailed blenny.  I keep the temp at 72F and allof the other water quality parameters are normal, but on the high side of the 
normal range.  As for my question: What should I add next, meaning what kind of
filter should I add.  I was thinking about adding an Ehiem canister filled with
X-nitrate and X-phosphate or a wet-dry.  Which would be more beneficial at the
moment?  Any ideas?  Which is the best wet-dry out there?  I heard Amiracle was
pretty good, at a decent price also!  Thanx in advance for any help.
