White spot all over fsh.... catfish all died
Hi ,

i set up my 55 gallon tank about 3 weeks ago . i have 7 anglefish , 5 catfish , 2 neon tetras , 2 painted glass fish , some looking skelton fish , and 2 gromies and 1 shark . i have a 35 to 60 gallon fliter system on it the heater was set to around 75 . Recently the fish got white spots a little and now fully covered . the cat fish have it really bad. 4 cats died and 1 angel fish. the and fish had like cotton on her wing and it was stuck fast. i bought COPPERSAFE and started to trest the tank and that is when the fish started to die fast. 4 in the last 3 days . so what can i do to save the fish whit out the whte spots

This seems like an awful lot of fish to have so soon in such a new tank, which may have contributed to how fast this seems to have spread. I don't know much about such outbreaks, but I think the best thing to do to save your fish would be to perform water changes and/or move the unaffected fish to another, well cycled tank.

Here is a link to what may be the problem your fish are going through and what you can do if this really sounds like problem:

Hi, and welcome...
The first thing I can say is that you should probably expect to lose more fish. That is too many fish in that size of a tank, and way too soon to have a fully stocked tank. Did you cycle the tank before putting fish into it?
In order for someone to help, we'll need to know the water quality stats for ammonia, nitrite, nitrate, and pH.
The first thing I can instruct you to do is to purchase some polyfilter if you have it available to you. If not at your LFS, you can find it at This will work much faster than carbon to suck the medication out of the tank, and to help soak up waste levels at the same time. The polyfilter should be changed after about 48 hrs, and a fresh piece put into your filter for another 48 hrs. Once this is done, the water will need to be tested again. Most important is to get that medication out of the tank asap without shocking the fish with too many or too large of water changes. Small, daily changes of 10 - 15% for a while will help a lot.
If your tank is cycling, which is highly likely at 3 wks old, medications can be deadly. Coppersafe is not a safe medication to use for all species of fish. Angelfish are sensitive to copper, as are most catfish and shark species. Until we know it's safe, I'm going to say it is best NOT to medicate this tank.
In addressing the stocking of this tank, angelfish grow to 8 inches in diameter for average, and are aggressive and territorial. You mentioned catfish, can you tell us what kind? It would help a lot if you could post pictures of your fish here for us to see, so we know what species we are dealing with. Angelfish also tend to eat neons, especially in a crowded tank. Shark... what type? These also are known to be prone to stress and illness during cycling, in crowded situations, or if not enough territory. The smallest of the freshwater shark species readily available is the red tail shark, and you are again looking at a fish that reaches 6 - 8 inches long... then there are bala sharks which average 14 inches... and irridescent sharks which average about 3 - 5 feet.
How often are you doing water exchanges? How much water at a time? How often are you feeding the fish? How much each time? A temp of 75 is borderline for most of the fish you have, and would be better at 78 degrees.
The more info about your tank and fish that you can provide, the faster we can all help you here. Pics are important if you can get them!
The chances are extremely high right now that your fish are suffering from poor water quality, not enough heat, overcrowding ( which causes stress) and from being mismedicated. How much territory (decorations and plants) is in the tank?
As I said, the more you can tell us, the faster we can help.

i feed the fish two pinchs of food either or. 2 to 3 x a day .

i change the water about 10 to 15 percent every friday .

the temp is 79 right now. i have no idea if it is in cycle .

i fill the tank with purfied water from my PUR water filter

I need to know the water params... ammonia, nitrite, nitrate pH test results. Until we know the answer to that question, there isn't much I can do to help... nor can anyone else. Medication is probably going to be needed, but if there is any ammonia or nitrite, or if nitrate is over 40, it'll need to be cleaned up and stabalized before adding any kind of medication. I am still browsing the pics to see if we can identify exactly what is in the tank, but from what I've seen so far, I'm definately going to stand on what I said about there being too many fish in this tank, especially this soon. Once well enough, most of them will need to be relocated. I wouldn't keep more than 2 angelfish in a 55 gallon tank, and eventually (usually within the first 1 - 2 yrs) they will need a larger tank. I would not advise keeping angels with the neons... and the catfish... maybe 1 can stay temp... I have to figure out exactly what species they are.
I'll watch for the water test results. IF you take the water to your LFS for testing, please have them write down EXACT NUMBERS and the name brand of the test kits they are using so I will know how accurate the results are. The best thing to do would be to get your own kits, since you will need to be doing somewhat frequent testing until the problem is resolved, and it's something that should be monitored regularly to keep the tank stable. I would suggest liquid test kits because they are much more accurate than the others.

here are the specs .

nitrate is 40ppm
nitrite is higher than the chart it read pinker than the 10.0 ppm color
hardness is 75ppm
total alkalinity is 80ppm
ph is 6.8

That high?:blink: You'll need to carry out more water changes.

paisley_tele 10-29-2006 05:43 PM

ya i figured that . i did a 10% last night . and dawn tld me to do one every night . so to nigh ti will do another
