#ed_op#DIV#ed_cl#oops sorry. I have a 55 gal tank that was established for about 3 years before I bought it. I have had it for about 6 months now and the fish that is infected is a recent buy, a coral beauty. She is3 weeks in this tank and I started noticing the ich about 4 days ago. The water is at 1.025 sg, ph 8.0, temp 76.#ed_op#/DIV#ed_cl#
