Ok so New question completed the 1st 7 days on day 4 of 1st dose my fish started flashing so I administered a second dose (no waterchange) flashing stopped waited for 7 days to finish (3 additional days) 30% water change put carbon back in and turned uv back on going to administer 2nd dose this wendsday my question, is it normal for them to start showing signs again so quick? After 1st dose some of my fish that showed no symptoms prior now show some, tile fish yawning 2 more anthias hiding looking more pale and I can see random size translucent spots on my gem tangs fins (only fish showing any spots) but all eating voraciously except the 1st anthia i was concerned about he does swim up to the top of the rocks and eats when I spot feed him still looks fat no spots I can see but def more pale
