^evil vilan in his layer lol and thats not a fish
Mine are my Turquoise (Lake Kutubu) Rainbowfish, and Hillstream Loachs I had a cuple Pseudogastromyzon cheni and want to get some Sewellia lineolat, even in the right tank set up tho they seem pretty hard to keep.
The Raindows are crazy colorful changing from black to forest green to Turquoise and the males? Have a iridescent yellow band from there nose to there dorsal fin that they seem to be able to "light up" when they want. You would never know half of this from seeing them in a fish store. I have been looking at other rainbows too but most you would have to go trekking through the jungle to find them.
