Four Sewellia hypsicrateae hillstream loaches.   Previously known as SEW01.  These are young F2 fish bred in my fishroom with hard suburban tap water.  Sexes will be random.  Since they spend most of their time grazing on rocks and picking through detritus, these should only be added to an established aquarium.  I keep my colony in a 20 long with the bottom covered in smooth fist sized, a sponge filter, and temps in the low 70's.  A rivers set up is not required as often thought.   They are happy to live with my Pseudomugil ivantsoffi and cherry shrimp.  The more common hillstream loach is Sewellia lineolata (also available in another auction of mine).   Those fish have a tiger stripe pattern.   These are much less common and have a fine spotted pattern.   I'm keeping several colonies of loaches right now and these are my favorite.  The young fish look like S. lineolata, but as they mature they transition from stripes and spots to predominantly fine spots.   I wish I could have got a decent picture of my largest adult, it's pretty awesome looking.
