1~What type of fish is afflicted? In addition, please describe what is wrong with the fish to the best of your ability (i.e. cotton like growth, bloated, etc.).
Currently, lesions that are purely white, or with slight redness surrounding.
2~What are your tank parameters (ammonia, nitrites, nitrates, temp, pH)? Please give exact values.
Ammonia: 0.5 ppm
pH: 7.6
Nitrite: 0.25 ppm
Temperature: 21 degrees C
GH: 179 ppm
KH: 72 ppm
3~ How large is the tank? How long has the tank been set up?
The tank is 22L, approx 5 gallons. The tank has been up for 4 weeks.
4~What type of filtration are you using? Please give the name and number (i.e. Fluval 304) and amount of [acronym="Gallons per hour"]gph[/acronym] if known.
Elite Hush 5. 60 GPH
5~How many fish are in the tank? What kinds of fish are they and what are their current sizes?
4 goldfishes in total (1 Common, 1 Fantail, 2 comets). All fishes are less than 2 inches long.
6~When is the last time you did a water change and vacuum the gravel?
How often do you do this? How much water do you remove at a time?
Last water change + vacuum: 2 days ago.
I do this at least once a week, but recently, once every 3 days with medication. I remove about 1/2 the water each time.
7~How long have you had the fish? If the fish is new, how did you acclimate it/them?
I received the fishes as gift 5 weeks ago. 4 fishes in a 5 L tank. They were stressed, and moved them into a newly purchased 22L tank 4 weeks ago.
8~Have you added anything new to the tank--decor, new dechlorinator, new substrate, etc.?
I haven't added anything new to the tank while they were in there. Everything in the tank now was in there before they were introduced into the tank.
9~What kind of food have you been feeding your fish, have you changed their diet recently?
I have been feeding them fish flakes since the beginning. Their diet has not changed.
I keep a brief diary of what I do to them and how they behave... I'll summarize below:
The fantail initially presented with white pimple like papules on its fins, which I initially thought was ich. Treated it with ich medication for one week, raised temperature to 26 degrees C as part of treatment. However, the white pimples grew in size, and became fluffy. Then red lesions with white centres started appearing in all 4 fishes. Realizing I misdiagnosed, I changed water 3 times over 3 days and lowered temperature to remove the ich medication. I then started them on Tri-sulpha tablets as recommendation from a local pet store. The redness disappeared around the lesions, so did the white growth. However, the lesions have more or less been unchanged in the last week, no observable healing or worsening is observed... I have attached a photo of the worst-afflicted fish... Please help
Many, many thanks,
Alex.
