I forgot to add about the black shark, i don't know an aweful lot about them apart from they big, nasty and need a big tank.
You never mentioned the "window cleaner" before, there is no such fish but i believe you are referring to a pleco of some sort like this;

What type of fish are you referring to when you say headstander?
As for tanks, if you want to keep the left over irredenscent shark you need to get a 200gal tank. If you want to keep the bala shark but not the ID shark you will need a 75gal tank and 2 more balas.
If get rid of all your fish apart from the convicts, they will be fine in the 30gal.
If you keep the piranhas you are going to need a separate 90gal tank all of their own, since they are not community fish that can be kept with any of your other species of fish.
I don't know much about whale fish, but from what i have heard they are very sensitive fish so probably won't last long in your tanks.
