I have a female betta in a 10 gallon community tank with 3 mollies and 3 cories. They all seem to get along quite well.
About a week ago I noticed that my betta had some white specks in her tail, and immediately started treating the tank with Kordon Rid Ich +, since I knew it would only be a matter of time until the rest of my fish developed it.
Because of the cories, I pulled my betta out and put her in a QT tank and treated with a full dose of the rid ich. The rest of the tank I began treating with half-doses (cories are scaleless and don't tolerate medication very well). After treating for 4 days. The betta lost her ich spots and becuse my QT tank isn't a great set-up I moved her back into the main tank and continued to treat that with half-doses.
It's now been 7 days, and my betta looks WORSE than when I started treating. None of the other fish ever developed any spots. The betta now looks terrible, and I feel awful. It looks like white chicken pox on her, she has that many spots.
I don't know what to do. She's not flashing (do bettas flash?) so at this point I'm not sure I'm convinced it ever was ich. I'm not sure if I should pull her back out and try a salt treatment (do bettas withstand those well? I didn't do it in the first place because they so stressful on some of my other fish), or pull her back out and keep treating with meds?
I'm worried about the stress that these prolonged treatments might be having on the rest of my fish, and I can see that it's killing my plants which I'd like to avoid (but obviously I'd rather kill the plants than the fish).
10 gallon, cycled 4 months, live plants, floating and sunken fake decor. Aquaclear 20 filter, heated to 76 degrees (right now it's more like 78-80 because it's warm out). Gravel substrate. Large airstone.
Normally change 25% of the water every 4-5 days, while treated been changing 25% every other day or every day if I have time.
pH - 7.6 normally (has been running high with the rid ick meds, closer to 8.0)
ammonia - 0
nitrite - 0
nirtrate - 15ppm
I don't add any additives to my water, I miantain water conditions with extra water changes if necessary. I do, however, use a Jungle water conditioner to remove chlorine and chloramines.
