That's one thing that I noticed in particular about this species of fish. Even in the wild they had impressive trailers on their fins.
Not sure where you acquired the Hogaboomorum (incidentally, the fish was not named after one guy, but two brothers named Hogaboom...thus the plural "um" instead of singular "us" at the end), but they could very well have originated from my wild pair brought back several years ago. I have two breeding pair of the fish, and lots of sibling throughout the tanks. It's a very cool fish..and it's found only in the Rio Cholteca in Honduras. Closest species to this fish is the Citrinellum. They share may of the same traits. The biggest male I have is around 13" with a much smaller female. When they hit about 5-6" you will easily be able to distinguish male from female by the color. Females will get a deeper orange (sometimes rose) blush...males a dark cream...some variation when they breed. Both keep their bars. Here's photos of the pair. Great fish. Enjoy.
