I went over to my sixty gallon community tank this morning with a female betta, gold twinbar platy, Bristlenose Pleco, female swordtail and two zebra danios. I was going to buy more zebra danios today, but seen that the regular coloured Zebra Danio has white spots on him. One on his head and one on his fin. So I decided that I would not get anymore Danios so not to transmit anymore ich. I am still stocking the tank probably if it is not overstocked yet. He is too fast to take pictures of to show you guys. My female betta in there who used to be in a five gallon, then ten, then twenty and now a sixty over the past almost seven months, previously had ich when she was in the five gallon two weeks after I got her. I used API Super Ick Cure when the heating the tank up gradually did not work even after two weeks of keeping it heated. That cleared it up. I am not worried about treating her and the other fish with it, but I am worried about treating the pleco with it. It says for scaleless fish to treat at half the normal dose since they are sensitive to this medicine. I know if I can treat them with this I will have to buy another bottle of the medicine to have enough to clear the ich up. I have heard that plecos are scaleless, so should I treat at half the dose to clear he ich? Or should I go and try the heating the tank up again and hope that it works this time with heating the tank up gradually? Sorry if I sound too confusing in this. I am trying to be clear but it is not coming out clear. If it is confusing to you, just tell me and I will try to clear it up again.
