Answer VERY CAREFULLY!
the problem with tanks like yours is that you cannot put inany of the traditional tank cleaners-they are food for the gang.
I have never had an aggressive tank, but in the large LFS where I used to work, the tanks with aggessives were kept with low light, only enough rock for the eels to curl up under and were cleaned very carefully indeed by scrubbing the rocks with brushes, siphoning off the detritus on the bottom and if necessary, removing rock from the tank for a morecomplete cleaning.
