How large do Coolie Loaches and Dwarf Loaches grow, and how many should I keep?
I think about purchasing Coolie Loaches or Dwarf Loaches. Since I found varying information about their sizes, these are my questions: How large can each of them grow?
Coolie Loaches usually grow to about 10 - 12 cm, single specimens occasionally grow slightly longer. If "Dwarf Loaches" refers to Yasuhikotakia (formerly Botia) sidthimunki: These fish only grow to about 6 cm.
How many of them should I keep?
They should be kept in groups as large as possible, at least 6 - 8 specimens. Since at least the Yasuhikotakia sidthimunki are rather lively, their aquarium should be at least 80 cm long.
