I had my p. semicinctas for ~10 years. They were great! Very people interactive, waiting for me to feed them from the doorway end of the tank. & freaking us all out when 2 "hid" in the floating plants. They got used to me reaching into their tank & didn't bother to move even if I slowly touched them.
I miss them so much! 1 of my all-time favorite "pet fish"...maybe again some day...(sigh)
In my opinion the Kuhlii Loaches are the best tropical exotic fish a guy could have . I don’t have any right now but the next time I see them I’m getting all they have . They are so comical and fun to watch . I love them .
