>>> Botia Lohachata
That is an old name, it is synonymised with Bota almorhae. These are commonly called Pakistani or Yo-Yo loaches. Like most Botias, they are boistrous, but are not really aggressive. Sizewise, there is some issue, you will commonly see reported that they only grow to 100mm/4", but several board members here, including me, have examples which are substantially larger. My biggest one is more 200mm/8". They do eat snails, although not with the same voracity as say Botia striata, they don't eat plants. They should be kept in groups of at least 3 fish. They have quite a lot of personality as Cyprinids go, and are very active.
If you search for yoyo you'll find a number of threads about them.
