Obviously they are climbing up beside or on the tank, the big danger is them pulling the tank over on top of themselves.
I wouldn't worry about locks for the lids, you have to keep the kids away from the tanks period.
Two and three year olds need constant supervision, either keep them out of that room with a locked door when nobody is with them, or move the tank to a room you can secure.
