I looked up pics of the amazon, where they catch plecs, and did my best to create a ''snag'' with stones, slate ,wood and pebbles, and since I re-scaped, I see them sometimes. I am sure they feel more comfy in ''natural'' look best to my ability.... yes , I also looked at the tanks ont he forums too, get great ideas and sometimes just gotta ::drool . You will know if too much stuff or not , stand back and look ... the tank will tell ya... just gotta have caves and choose were the plecs would prefer to hide, obviously not in front, by glass...HTH ,
