I'm not an expert on this but as far as i think those develop due to unbalanced strains, to avoid further cracks avoid straining the tank i.e. do not let it lie sideways. try to keep it upright on its base and also while moving it avoid bending any part as that will increase the cracks.
as for the already formed cracks i suggest applying a suitable layer of silicone rubber it will not look good but will prevent leaks.
by the way what size is the tank?
