My tropical, including catfish, "suckerfish", shark all have ICH. Have fish for about 2 yrs and hubby bought a lgr. 29-gal tank and about 6 more fish. (about 12 total) I took the filter out and raised the temp to 66*-68* and turned off the UV light. Please help..these were a gift to my son and I don't know what to do.
68 is about 20C what was it before (are you sure this is correct??) raising the temperature won't do anything to kill ich unless its over 82F (ich dies at this level), if you are going to increase it that much, do it VERY slowly over several days.
