I have a new 10 gallon tank. I put in 3 platties, a sunset, golden, and micky mouse. 2 weeks in they seemed to be really healthy and happy, so I added a dwarf african frog. 2 anubias plants and driftwood, at which point I also did a 15% water change to make sure the water wasn't getting toxic.
When I did this water change I noticed the sunset platty had a white spot on its top fin. The I noticed the gold one was reclusive for the last couple days as well. This is when I researched all I could about Ich. I am a beginner, so I tried my best, but I realize I may have stressed them out too much.
Within 24 hours of noticing that first white spot, the fish fins got covered in white spots, the gold one getting it the worst in her gills and all over, severe infestation. I immediately ran out and all I could find at my pet store was Ich Attack by Kordon, a non toxic herbal treatment which I was assured by the employee was effective and what they used on their tanks.
I don't trust herbal remedies, so to support it I also dosed the tank with salt 1 tbsp per gallon. I raised temperature to 86degrees to speed up the cycle and removed the carbon filter. On day 4 the infection got worse and was not getting better. At this point I raised temperature to 91degrees. Within 24 hours the platties were cleared of any white spots, except the golden one... who now had more spots than ever before and couldn't breathe even at 86 degrees. She passed away on day 5.
Raising the temperature to 91degrees seemed like the most effective method. So I did a 50% water change to normalize the salinity and remove the herbal medicine, and I replaced the carbon filter. I am in the middle of day 6 and they lost all their white spots on day 5. Should I keep the heat at 91degrees until day 10? Or is it safe to lower the heat by day 8?
I know, I put them under alot of needless stress, but 2 out of 3 pulled through, and I learned how to deal with this disease. I ran out and bought some malachite green for the future, although I don't want to put it in the main tank. Would a 1 gallon bowl with gravel and water from the main tank serve as a good quarantine tank to dose new fish with malachite green? Also, when I do this, do they need to be in the quarantine tank for 10 days?
I plan to get a neon blue dwarf gourami in 2-3 weeks when the water is cycled, to finish my tank. So it would be 2 platties, dwarf frog, and a dwarf gourami in the end... maybe one more platter or tetra over time.
Sorry for the long post, but I appreciate anyone who takes the time to read it and respond.
