Most loaches are rarely, if ever, bred commercially & only accidentally in home tanks. They are almost all wild caught, although some like y. sidthimunki are bred using hormones. Not pangios (kuhlis) AFAIK, they are wild fish.
Depends on Law of Supply and Demand. I get them cheap though.another question: how much do kuhlis usually go for? I know that price varies from store to store, but what did you pay for them? I didn't want to start a new post since this is the same topic.
As far as I know, Pangio kuhlii, Pangio semicincta and Pangio oblonga are the few ones bred so far without the aid of hormones.
