After having my newest tank up and running for over a year, I recently had a sudden onset of Velvet (at least, I'm fairly certain that was the culprit). During the course of the year +, I have had 1 fatality in the system (a blue cleaner goby) - the other 10 fish have been very healthy. Three days ago, I noticed my fish were covered in white spots - I thought it was ich at first, but after closer inspection, realized it was a golden hue and had a cotton-ish appearance (similar to fungus). That evening (about 10 hours after noticing the outbreak before heading to work), 1 fish was dead. I tore down my 90 gallon setup and moved all of the fish to quarantine (identical params as the main tank - new water). The next morning, 2 more fish...dead. By the end of the second day in quarantine, I had 4 fish remaining. Today, I am down to 2. The ONLY change I have made to my system was the addition of a lawnmower blenny (about two weeks prior to the outbreak) and that same day, I purchased some bottled mysis shrimp -though all 3 of my systems have been given that food source. The lawnmower blenny was one of the most recent fish to perish and initially, did not show any signs of the disease, so I'm not certain he's the culprit.
Does anyone know what could cause a sudden outbreak of such a deadly disease? ** I did do 2 water changes (aprox 25%) over a 7 day window to eradicate some hair algae, but it's my own RODI source from home that all of my tanks receive. I'm scared to add any new fish after such a catastrophe. :sad:
