I was considering getting some kuhli loaches ( later ) but the 1 local pet store ( havent checked the other 2 ) stated he doesnt carry them cause out of 2 dozen only like 3-4 will live past a week. Is that a basic problem with them? Are they hard to care for is it maybe just his supplier? I will check the other 2 local stores later this week and see what they say, just wanted to hear some info from people that own them or have owned them
