Today we were having a birthday party for my daughter and guests started to arive. Well the first thing she did was start to show the guests my reef tank. I few seconds later she came up to me and told me all my fish were laying on the bottom of the tank dead. Well nothing gets your heart going faster then being told that your fish are dead. Well as I walked up to the tank I noticed all the fish are laying on the bottom, but not dead. Well I quickly noticed the back end of my stupid black cucumber (I always hated the thing) sticking out of my Mag 5 pump. Well as you can tell the cucumber got stuck in the pump and was chopped up. I had two other tanks that were cycling and I pulled all the fish out and put them in the other tanks. I figured that was better then letting them stay in the tank. I did a 50% water change to. Nothing like doing a 50% water change with a house full of guests and kids. You are sitting there freaking out that the whole tank is dead and they are all comenting on how beautiful the tank is. To me a bunch of colorful fish laying on the bottom of the tank, and a bunch of closed corals is not beautiful. Well I lost my yellow and purple tang, and my fox face rabitfish. I also think I lost my goby. My clown is hanging in there, but I am not sure if it is going to pull through. After I did the water change all my corals opened up againg. Does cucumber poison affect corals? What should I do now? I will do another water change tomorrow, and another large one on Tuesday. Should I run some carbon also? I figure I need to wait about a month before I add anything to the tank. The only thing is I have a T. Maxima clam being shipped that I will have on Tuesday. My other two tanks just are not ready for anything yet. Any advice would be greatly appreciated as always.
