Tank size: 29 USG
pH: 7.8
ammonia: 0
nitrite: 0
nitrate: out of fluid
kH: unknown, but fairly high
gH: unknown, but fairly high
tank temp: 80 F
(yes, it has been cycled)
Fish Symptoms (include full description including lesion, color, location, fish behavior):
One by one, my Harlequins seem to leave the shoal, and twitch until they pass away. They will still respond to stimuli, such as another fish swimming by, and I have seen them feed in this condition. Toward the end, they seem to get a bit of a white coating along the top of their body, and I noticed the tail fin was degraded on one of the unfortunate victims. It was more of a coating than spots or growths. It didn't look cottony. Dead Skin possibly? Fungus? Bacteria? Columnaris? Neon Tetra Disease? The fish seem to last about a week between when the twitching starts and when they pass on.
Volume and Frequency of water changes: At least 5 gal once a week. Sometimes more. API's Stress Coat for conditioner.
Chemical Additives or Media in your tank:
Marineland Penguin 200 filter packs do include carbon. It has a biowheel for the bio filtration. I know I should remove carbon with most medicines, but I suspect that a significant amount of my good bacteria are on my filter pack. Should I gut the carbon out of it and leave the rest of it intact?
Tank inhabitants:
8x Pacific Blue Eye (Pseudomugil signifer)
6x Harlequin Rasbora, down from 8x
5x Emerald Green Cory (Brochis Splendens)
1x Pearl Gourami (Trichogaster leerii)
1x Clown Pleco (Panaque maccus)
Recent additions to your tank (living or decoration):
The Harlequins were added with a sword plant of some type and a bamboo. The first harlequin started twitching about a week ago, when and because of the degraded fin, I suspected fungus and added the fungus treatment. The first fish passed, then a second one got sick and then I added the treatment again. The second fish passed, and then after waiting a while added the gourami and pleco. Now the 3rd fish has gotten sick. None of the other fish in the tank have shown any signs of illness.
Exposure to chemicals:
Tried using Jungle's "Fungus Clear Tank Buddies" (active ingredients: Nitrofurazone, Furazolidone, Potassium Dichromate)
I bought some Maracyn plus antibiotics, but haven't added it, waiting to make sure it won't damage my Filter Bacteria.
Digital photo (include if possible): current fish has no external symptoms, other than twitching, yet.
