背棘 (总数) : 8 - 11; 背的软条 (总数) : 9 - 11; 臀鳍软条: 6 - 8; 脊椎骨: 36 - 38. Presence of seven paris of branchiostegal rays; nuptial males have a blue throat; subdued body and fin markings; absence of bright or dark green coloration on the flanks; pectoral-fin base without scales.
出现鳃条骨的七 paris; 求偶的雄鱼有一个蓝色的咽喉; 抑制的身体与鳍斑纹; 在侧面上缺乏明亮或深绿色的颜色; 胸鳍基底没有鳞片。
Most often occupies open (not vegetated) although complex bottoms comprised of gravel to cobble-sized fragments of tufa and tufa stromatolites. This substrate is formed largely by calcareous material accreting through physical and biological precipitation of calcium salts as well as by transport of fragmented tufa from upstream that deposits to form armored bars where channels widen abruptly.
大部分时常占领开放的 (不是长满植物) 虽然复杂的底部包含了凝灰岩与凝灰岩 stromatolites 的砾石到圆石规模碎片。 这一个底部主要地被经由钙盐的物理及生物沈淀生长的石灰质材料形成以及藉着碎片的凝灰岩的传送从向上游那沈积形成峡道突然地扩大的厚重的横带。
