Bristlenose destroying my tank!!

I agree the bristelnose are responsible for the sword damage. My single destroys any you put in there.

Feeding extra will help, but they love swords, IME.

Others have not had this issue.

The Rotala might need pruning. I have had this blackening of the stems before and I usually prune and trim, as the lower leaves/stems are not getting any light and the mass affects flow/current. Rotala can get pretty thick in there when it grows well.

Take some tops and plant about 1-1.5" apart. They grow back quickly.

I have this issue less since I dose EI...........

Good luck,

 

Never again will I add Bristlenoses to my plant tanks containing swords. I put 2 in my 240 gal. that had a couple of 24" plus swords. In a matter of days they completely destroyed most of the leaves before I was able to catch them. It will likely take a good while for them to grow back to their original size.

 

I've had two BN Plecos in my 72 gal planted tank for almost a year. And with two swords and a load of other plants. Other than occasionally knocking a newly planted stem when they were rooting around like normal I've had no problems. It might be keeping them satiated. I do drop a few algae wafers or Hikari sinking tabs 1-2x a week and every 2 weeks or so cut a piece of english cucumber (this one does not cloud the water like zuch's or the regular "fat" cucumbers) and tie it to a small stone and sink it to the bottom. They find it in about 2 minutes. They LOVE it. It's almost gone in one day.
