HELP! We just noticed that the center support of our glass 240g has come loose/off. It has separated from the front of the tank almost 1/2". 
We moved the dats and the aro's to another tank, but still have 3 rays in the tank.
We have drained just over 1/3 of the water and the front seems be have come back. But don't know where to go from here on the fix. Can we just clean and silicone with water/fish still in the tank? Do we have to drain the tank completely?
Thanks for any help or suggestions.
-Just another 11:30pm emergency-
