So i bought a common pleco taking the risk of them living in my p tank, well that lasted about 5 min walked back into my room half his body was gone poor pleco, crazy i fed them alot of worms before i put him in the tank
I'm not piranha expert, but I think you might have had better luck if you would have waited a couple hours after the feeding to add the pleco, that way they might have been less likely to see it as food.
I had a pleco that lived with my 4 RBP for four months. One day I couldn't find him and as I was looking around for him just the bone of his head was in the corner of the tank. Sorry about your fish.
I know your Ps are pretty small, what 2-3 inches now? So how big was the pleco? Sounds like it must've been tiny. If i recall right, you also have no hiding spots?
I also added a pleco to my RBP tank. I did it at night, but he still got a nice big chunk taken out of him...he is fine now and getting quite large. To heal his wound, I dabbed bacitracin (sp?) on it daily with a very long thin paint brush. I forget where I got that advice on MFK but it worked!
