Can someone help me confirm whether this is ich for sure or not? I have been treating with Ich X for around 5-6 days now and the condition has only got much worse in that time. I sent the photos to a vet acquaintance and he said he thought it could only be ich or velvet from the pics and the treatment would be the same either way.
I had what appeared to be ich in a few of my other tanks that went away after 1 or 2 doses of ich x. I believe I spread it because I moved some fish around for aggression reasons before I noticed any spots. I continued treating for a few days to make sure it was gone and it hasn't returned in those tanks. This was the last tank to develop the symptoms. However, so far the condition keeps getting worse every day in spite of the same treatment. The spots look the same as the other tanks that had them, but they are much worse in this one. I have been doing daily water changes with the treatments for the past week or so. I am seeking some advice because I have kept fish for 30 years, but I have never had ich that has progressed this far in spite of treatment.
This is a 40 gallon breeder that is set up as a quarantine tank. There are 5 oscars, 1 clown knife, 1 royal pleco, 1 fire eel, and 1 silver arowana. I have only had these fish for a couple of weeks. They are all very small still and will be moving to a 500 gallon tank once they have some size. There is no substrate in the tank, but there are some pvc pipes and potted plants, and a couple of pieces of lava rock. There is a heater and an aquarium coop large sponge filter in the tank with an air stone.
Water parameters:
NO2 and NO3: 0 (daily water changes), ph: 7.2, GH: around 8d, no chlorine detected. Temp has been around 78 degrees. I recently raised it to 80 degrees. Many more spots appeared after raising the temp slightly. I have been reluctant to raise the temp further because that is the only thing that has given me negative results in the past from what I can tell.
As I mentioned, I have been treating with Ich X daily with the recommended dose and conditioning the water with Ultimate as recommended to avoid the sulphur reaction. These fish also went through a treatment of PraziPro. I also thought about trying salt, but was strongly advised against it by the vet and a couple friends who thought some of the fish would be too sensitive, especially with the progression.
I am hoping someone can give me some advice on anything else I can be doing. I have only been doing 1 dose a day because of the clown knife and the eel. The only thing I can think of is to do more treatments a day and hope for the best. Any help would be appreciated.
