Since it's quiet in here, thought I'd add a weird experience I had last week. I've developed a harder to clean dark green algae on the bottom and corners of my tank. The mag float wasn't getting it done so I got a Kent scraper with the razor blade and 10 gallons of saltwater last week. Removed enough water to rinse the scraper off before using it and got to work on the front and one of the side panels of the tank. I noticed my 5 chromis were all acting weirder than normal and breathing really heavy so I stopped there and did the water change. Within 30 minutes, I removed 3 that has started to lay on their sides and go belly up somewhat. The fourth was completely dead the next morning and the fifth hasn't been seen since it all started so I'm assuming he's somewhere in the rock work rotting. I found other mentions online of a rapid chromis die off like this and it's always been centered around an algae cleanup operation whether glass or rock related. I have clowns, yellow tang, lyretail anthias, and a canary blenny left and all have acted normal throughout. No coral ever reacted to any of it either. Any ideas or suggestions going forward?
