Yeah he's a Kuhli Loach. (Pangio Semicinctus). There's about 10 differant kuhli species but the lfs often sell Pangio Myersi the most. Here's one of my Pangio Myersi.
Love your photos, love your loaches, love your plants. Was there a front shot of the tank still to come? Right, you said your batteries were charging. Look forward to nominating you for TOTM.
P S Almost had me a Khuli -- went back to get it and they had sold them all!
