Alright here goes. Im not sure what is going on. I think its ick but im not sure. I have had all my fish in this tank for about 1 1/2 years. Anyhow to make a long storie short. I have never had any kinda out break in any of my tanks. My tank is 75 gallon tank, and contain mostly fish. Over night my Iridecent and bala shark have broken out with white spots all over. Even on their eyes. I did not catch this till i got home from work, so its prob set in for awhile. This all started because i was a bit behind on my reg tank cleaning. I must have stirred somthing up in the gravel. I vacked the gravel and did a 1/2 change. But now they are covered in these spots, and it came on quick. I put some ick away, followed the ususal dosage for scaleless fish 2.5 ml per 10 gallons, slowly raising my temp to 84 degrees. Anyone have any ideas? And does it sound like ick?
