I tried an xenia a couple days ago. And my tank is 2 months old but only one of those 2 months has had fish, the fish have been I'm for 5 weeks so was it early, it melted disintegrated almost. My nitrite was pretty high... Everything else is good my two clowns the rest of levels are fine nitrates a little high about 10. But I couldn't get any pictures because it happened while I was gone.
