u prob mean these guys ?
Sahyadria denisonii
i had a group of 7 huge ones in my 210g - they get large and need a lot of swimmig room. i considered putting them with my discus but they are very fast swimmers, always on the move, and i felt it would disrupt the discus too much so i didnt mix them. lots of ppl do mix them with discus tho.
one word of caution - i recently rehomed a lot of my fish including my group of 7 toroedo barbs. it was a most horrible and tragic experience... 5 of the barbs "slimed" themselves to death. they must have been so frightened during the move that they released slime in defense, it clogged their gills and mouths and filled my net so much that water couldnt pass thru the mesh. i tried to pull the jelly out of their mouths and gills and place them back in their main tank but it was no use... 5 barbs died of suffocation... i had never seen anything like it! so be very gentle when moving them, wouldnt want that to happen to yours...
