Black spots

Recommended Posts

Hi All,

 

It has been a while since I last post due to taking a break from this hobby. However about 6 months ago I start to get into this hobby again and bought a 40 gallon breeder tank with 1 ranchu in it. About 3 weeks ago, I added two additional goldfish in it (an Oranda and Ryukin) to give the ranchu some company but so far has been problematic.

 

Here is the condition of the tank right now:

 

  • Test Results for the Following:
    • * Ammonia Level(Tank): 0
    • * Nitrite Level(Tank) : 0
    • * Nitrate level(Tank)  15
    • * Ammonia Level(Tap) : NA
    • * Nitrite Level(Tap) : NA
    • * Nitrate level(Tap) NA
    • * Ph Level, Tank (If possible, KH, GH and chloramines) NA
    • * Ph Level, Tap (If possible, KH, GH and chloramines)   NA

      • * What is the name and "size of the filter"(s)? Aquaclear 50 + Aquaclear 70 (Added 2 weeks ago with new goldfish)
      • * How often do you change the water and how much? Average once a week - 80%
  • * How many days ago was the last water change and how much did you change? 4 days ago  - 80%
  • * How many fish in the tank and their size? Ranchu - 4.5 inch, Ryukin - 3 inch, Oranda - 3 inch
  • * What kind of water additives or conditioners? Prime. Recently use Prazi Pro to treat new arrival of the fish including the Ranchu
  • * What do you feed your fish and how often? Give the brand, type of food (sinking/floating pellets, gel food, steamed vegetable, etc.), and how frequently you feed each. - Azayaka - Green sinking pellets 

     

  • * Any new fish added to the tank? Oranda and Ryukin without quarantine. 
  • * Any medications added to the tank? PraziPro (4 days ago)
  • * List entire medication/treatment history for fish and tank. Please include salt, Prazi, PP, etc and the approximate time and duration of treatment.  Prazi Pro
  • * Any unusual findings on the fish such as "grains of salt," bloody streaks, frayed fins or fungus? All 3 develops black dots/marks.
  • * Any unusual behavior like staying at the bottom, not eating, etc.? The Oranda starts to bottom sit if I am not around. All 3 eats without problem.

Welcome back and I hope your fish feel better. To help speed things up, I know the D&D mods will want a picture or video if you have any. Black spots on goldfish are sometimes a sign of ammonia burns and or superficial trauma on the goldfish that is healing (scabbing over). Pics would definitely help though to try to pinpoint your problem! Bump!

Sorry to hear about your fish.

 

Please post your tap water parameters and ph for both tap and tank.

 

Did the black marks and bottom sitting start to show up after the addition of the prazipro?
