This is a discussion on Ich on 1 fish only out of 19??? within the Tropical Fish Diseases forums, part of the Freshwater Fish and Aquariums category; -->
This might be my first case if Ich :( One of my emperor tetras has a few white spots that look exactly like Ich ...
I see no reason to isolate a fish if this is in fact ich. The water is what needs to be treated, not so much the fish. If this was a species tank with only a few fish, then the fish could be isolated for 7 days or so and treated, allowing all theronts to die from lack of host. But your tank is a mixed community, and removing all fish is probably not practical.
Yours is a live plant tank, yes? In terms of recommending a medication I will leave this for the plant people here.
When you do the water change, it would be advisable to remove water directly from the surface of the gravel, where the tomonts would likely fall and be waiting to hatch. Removing tomonts manually with a water change can be effective at limiting the spread of the parasites. I have in some cases done 5 small water changes daily directly from the bottom when fighting ich in freshwater tanks. The difficulty is keeping the medication properly dosed, so this is also not a perfect concept. But it does help during the period of time you are waiting to decide on the appropriate treatment.
Romad- I hit the "my aquariums" tab and don't see the tank listed. Planted and with who for inhabitants? The one time I treated my display tank for ich I used the heat/salt method but after two weeks the ich wasn't budging and my plants (and catfish) were taking it in the shorts due to the prolonged use of salt and high temps. I resorted to using Kordon's Rid-Ich+ with great success. If I ever experience ich again I will use this same medication.
I did not do any water changes during the medication period for the same reason Pasfur states. I would not have been able to properly regulate the medication levels. I did a huge water change prior to the introduction of the meds.
I used the Kordans at half strength due to the loaches, catfish and otos in my tank. I know that Byron uses Aquarisol and highly recommends that medication. Good luck.
God I love this forum!! And yes I've got to update my aquarium stats. (Doh!)
My community consists of Boeseman Rainbows, Serpae tetras, Emperor tetras, Pristella tetras, Green tiger barbs, 5 cories. Pasfur, I do not have live plants. They're all silk at the moment. I'll be using live when I set up the 75 gallon tho.
And I do have Kordon RidIch+ on hand. Whoo Hoo!
So, it sounds like a nice big water change, gravel vac., and 1/2 doses of the Kordon to start with.
Thanks to both of you Pasfur and Aunt Kymmie. Great advice as always.
