A juvenile Pakistani Loach or YoYO loach or Botia almorhae from my tank. This beutiful loaches are native inhabitants of the water pool areas of highland streams. Keep driftwoods, rocks and plants in your tank creating lots of hiding places. Finer sand substrate is ideal for this fish, as their habit is to dig into the sand searching for food. Usual feeding habit include, sinking pellets, algae wafers, chopped earthworms, thawed frozen Bloodworm, Mysis Shrimp, chopped cocktail shrimp. Try to avoid over-feeding as these fish are very greedy. This species is an avid consumer of snails, making it essential 'housekeeper fish' for that aquarists having snail infested tanks.
Check out the marks on its body that resemble 'Y' and 'O'. The fish got its name 'YoYo' from the marks that resemble the same on their body. Again, 'Y' & 'O' marks could be found only on the jouvenile specimens of this species. The marks change and bevcome more random as they grow up.
The particular speciment, shown in the picture is little stressed (check its folded dorsal fin) due to the transport. I have taken the picture just after it is released in my 42gl South Asian Loach set up.
