so I recently grabbed a little LSN, about 5 inches long, from my lfs. He was sitting there for SO long, literally, like, 5 months and was always with aggressive tankmates like pacu. I felt so bad for him, so I finally caved and took him, but he's just SO shy and still cowers in the corners. I filled his tank with many, many plants and a large driftwood so he could feel safe, but he just sits in the same spot under the log. He has a great appetite and LOVES earthworms, so I know he's at least healthy, but is there any way I could make him happier? Would he like sand?? Another log??? More plants????
