They are now about 6 cm long and are very peaceful and tolerant fish. Botia rostrata is sometimes referred to as Twin banded loach or Seargant major loach. The pattern of twin stripes differs from specimen to specimen but the number remains the same. I'm attaching a pic I took today of a B. rostrata. This is a very peaceful fish that is recommended for any home community aquarium.
Juveniles are more active than adults, and spend their time looking for leftover food.
This particular species grows very fast, as my 4 have grown .25 inches over the 2 weeks I have had them. Adults have a golden metallic shine to them, and have navy blue bars and dots. They prefer to be kept in groups of 4-6, but be careful when selecting them. I bought small specimens before, and they were all gone the next day. Do not keep them with aggressive or large catfish or other predatory fishes.
