i was at a lfs and they had like 5 6in cls with spots, i bought one but later brought it back because he did not complete my pack of smaller loaches, but now on two of my loaches spots are appearing that were for sure not there when i got them. This is good because i now have my group of 21 and am looking for oddballs now, but in stores and the 1-3in size i am not seeing any spots.
