白金塞子燈 (Hemigrammus sp.)
由於近月水族商輸入野生寶蓮燈的批量每下愈況, 直接影響了我從該種內挑雜燈的機會, 現只好將目光傾向於野生金燈方面, 幸好近期收獲也算不錯, 先後在兩批白金燈之內, 淘到了兩隻白金子彈燈; 來自哥倫比亞梅塔流域上游 (Upper Rio Meta) 的子彈燈, 外型有點 Moenkhausia屬加拉辛的影子, 頭型圓大, 口部寬闊, 目光銳利, 身型就像子彈一枚, 雖然如此, 個性卻是相當溫和, 而色彩也很豐富, 眼睛上虹膜呈橙色, 體側長有不明顯金色亮線及尾柄與尾鰭交接位置長有一顆圓形黑斑, 通體被金色所覆蓋, 極盡華麗, 是我近期的至愛

騎士鉛筆燈 (Nannostomus eques "Rio Orinoco")
騎士鉛筆燈 ((Nannostomus eques), 俗名 Hockystick Pencilfish, 由於外型像似馬球棍而得名, 尾鰭下葉及臀鰭呈暗紅色彩, 但日常會被身體基部, 由吻部伸展至尾鰭位置的黑班所覆蓋, 黑斑會隨狀態表現時深時淺, 並喜愛集結於有掩護物如枯木或水草叢的地方活動, 泳姿有如在水中飄浮的梗枝, 藉此被過獵食者的攻擊, 個性非常溫和;
而騎士鉛筆燈的產地分佈廣泛, 以下是節錄自seriouslyfish 對該種的產地報告:-
Described from the Peruvian Amazon above Tabatinga, the latter being located in the Três Fronteiras region of Amazonas state, northwestern Brazil, where the borders of Brazil, Peru, and Colombia meet.
It’s since been recorded throughout the central and upper Amazon region in Brazil, Peru, and Colombia including the rios Tapajós, Trombetas, Madeira, Negro, Japurá, Içá, and Putomayo, and is also known from the Orinoco drainage in Venezuela and and Colombia (Guaviare and Inírida tributary systems) plus various rivers of Guyana including the Essequibo and Curuni.
Genetic reserach has revealed that populations from the upper and middle/lower rio Negro in Brazil represent separate evolutionary units and do not hybridise at the one locality where they occur sympatrically (the Igarapé Jacuná, a tributary of the middle Negro).

紅肩螢火蟲燈 (Hyphessobrycon sp. "Amapa")
最初以為這種紅肩螢火蟲燈, 跟其他螢火蟲燈般, 觀賞重點只在於尾柄上的亮斑部份, 但經飼養過後, 對牠的感覺可謂耳目一新, 這種原產自巴西阿瑪帕省 (Amapa) 某流域的小型加拉辛科, 從購入初時, 由於仍處幼魚階段, 色彩毫不起眼, 及至養穩後, 體側亮線及肩背上那紅色色彩才漸漸展現出來, 而腹部更泛起青黃的光澤, 表現極為讚嘆!
