Its been a sad weekend in our house. Our 90 gallon tank had a crash and we lost all fish in the tank however all the corals are looking great. Over the last 72 hours I have lost a harlequin tusk, yellow tang, 2 platinum clownfish and a humu humu trigger. However all my corals look great. No idea what is going on. Tank is a 90 gallon and has been set up for 10 weeks. Everything was eating just fine the day before their demise. The tusk started swimming erratically for a day and we noticed the top 20 percent of his body looked pale and then the next day he was sucked up against the overflow
The yellow tang had a small case of ich over the past 3 days or so. We have been feeding everything LRS food with a couple drops of garlic on it. This morning he was looking pale and then around 1pm he was done for. Eyes looked a little cloudy. Their is obviously something in the water affecting fish buy all my frogspawns and mushrooms and other corals are looking great. I have done a 15 gallon water change yesterday. Will do another 15 gallon on Wednesday. My plan is to cycle out around 100 gallons total over the next month and hope everything is ok by then. Part of this hobby I know but still sad.
