Hi everyone. I have been posting all my basic goldfish questions over at yahoo answers out of convenience, but I am starting to find that very few people over there actually have any experience in keeping goldfish. I am hoping that someone here has some more reliable information that can help me determine if my fish is starting to develop fungus and should be treated. The fish (Felix) is a basic fantail goldfish who came from nnnnnn. They had him in a large vase priced as a betta tank when I found him and he was swimming circles around the surface of the water gasping and likely suffering from early ammonia poisoning. I got him home and into a temporary ten gallon. He stayed there for about three days while I secured a 30 gallon tank for him, which he has been in for about 2 weeks now. When I first got him home I noticed that he had a single white spot, about the size of the head of a pin, on his tail fin. It did not look at all like salt, just like a slight white bump on the side of the fin near the lower edge. I resolved to monitor it closely, and sure enough it flattened out over the next couple of days, leaving only a flat white area where it used to be. The area is not fuzzy or bumpy, but it is not completely clear either. He did have one pectoral fin that looked half eaten, but is now beginning to grow back, so I am certain he had some fin damage when I got him. The strange thing is, it has been two weeks and he is eating great, swimming around like crazy, and white patch has not spread. No new patches have appeared, it just looks like the original bump spread out a tiny bit as it flattened, almost like a chunk of ice melting. Is it possible that this is just damage that is healing? I feel like a fungal infection would have spread or significantly changed size and shape by now, but this hasn't. The reason I ask is that we have a new oranda in quarantine who is almost ready to get transferred to the primary tank which Felix is in. I wouldn't want the new fish to get infected, so I want to be sure Felix is healthy. I have been watching him for the whole two weeks and the problem hasn't gotten worse or completely better. Can I assume that no change means it is just a scar or something and not a disease? How long would it take for a fungal infection to show signs of worsening if he did have one?
[*]Test Results for the Following:
[*]Ammonia Level? Unknown. We used a bottled bacteria to cycle the new tank so it should be stable.
[*]Nitrite Level? see above
[*]Nitrate level? see above
[*]Ph Level, Tank (If possible, KH, GH and chloramines)? I do not have a test kit so no exact reading, but I know our water runs slightly high on the Ph
[*]Ph Level, Tap (If possible, KH, GH and chloramines)? see above
[*]Brand of test-kit used and whether strips or drops? N/A
[*]Water temperature? 74-76
[*]Tank size (how many gals.) and how long has it been running? 30 gallons, running for about 2 weeks after using biological agent to speed cycle
[*]What is the name and "size of the filter"(s)? Filter is Tetra ES 20-40 power filtration system
[*]How often do you change the water and how much? We have changed about 15-20% of the water every week or so.
[*]how many days ago was the last water change and how much? The last water change was about three days ago, I removed around 6 gallons.
[*]How many fish in the tank and their size? One fantail goldfish, he is approximately 1 3/4'' long including tail
[*]What kind of water additives or conditioners? We use prime as a water conditioner/stress coat, we also added StartSmart bacterial agent to quick cycle.
[*]What do you feed your fish and how often? I sit beside his tank and feed him a small pinch of flakes. If he eagerly eats it all I feed him a couple more, until I notice he is taking less interest or seems full. He is given thawed and de-shelled peas (1/2 pea twice a week)and sun dried baby shrimp twice a week (2-3 shrimp per feeding). I give him two feedings a day, one in the morning/early afternoon, and one before bed at night. Again, I monitor him and only feed him as much as he is interested in eating at one meal.
[*]Any new fish added to the tank? no
[*]Any medications added to the tank? no
[*]Any unusual findings on the fish such as "grains of salt," bloody streaks, frayed fins or fungus? Just the single white dot which has now flattened down to a small blotch of white that stands out from the surrounding orange tail fin.
[*]Any unusual behavior like staying at the bottom, not eating, etc.? None
