Could anything survive in this water?

Wild minnows would do best in that type of water.

But they would do better in...well better water.
 
the creature from the black lagoon? :joke:

everyone who said some readings would help are right on. that would tell you how bad your pollution is in there and then you'd know how much water needed to be changed out to make the tank conducive to staying alive ;)
 
Forget cleaning it, the "look" is awesome. Just do water changes to bring down DOCs and nitrates, then stock it with some sunfish (how big is the tank). I love wild looking tanks, and that one is pretty wild.
