[Az-Geocaching] Should I archive this cache?

[SquishyGecko]

I've noticed that one of my caches, "Gecko's Sea Creature (GCJ7H6)," was
placed a mere 23 feet from an already existing first state of a multicache
(GC5173).  I recall hearing that it's common to keep your caches at least
528 feet from another.  I'm thinking I should archive this cache, however
nobody's really said anything.  Any thoughts?

Thanks.
