Ok, so I picked up a possible pair of LDA72's from Jeff on Friday. They are in a 125 with some small breeding geo ipos, same size breeding krobia sp xingu, columbian tetras and a single parancistrus (the one that was bullied in the group, maybe 3" tl). The LDA 72's are maybe 2"-2.5" TL. There is a large stump in the middle with branches coming out for cover and a few rocks piles to hide in. This morning I noticed that the bristlenose both had battle damage on the base of their tails. I didn't see them fight, but is it possible they did it to eachother when they found eachother or do you think the parancistrus did it? There is plenty of space for them all.
