I had them in the past, I will likely get more
they are neat fish. One of the reasons I didn't carry them more is they are absolute obligate Aufwuchs eaters. Now that this food is available, they can be easily fed
I've got some Stiphodon sp. (have no idea, which species, but definately not percnopterygionus, not even closely that stunnigly colored), they like black worms, so feeding hasn't been a problem for me.
I would LOVE to get percnopterygionus.
