great pics man, just got around to checking them out. will add some of them in the next update to LEP.net and primitive fishes.com.
the "hybrid" is a very interesting fish...the snout issue may have caused a reduction in length (of snout) somewhere along the line...swelling of the nose also indicates something happened somewhat early on. the gar looks like a really thick longnose, but the caudal peduncle doesn't match up with that of the typical longnose (more of a FL or spotted...but since the latter is almost non-existent in the hobby, i would lean more toward FL).
also love the African arow...that's seriously one of my favorite species of primitive fishes...and air-breathers to boot. will have to nab another one sometime in the relative near future...and yeah, it was never afraid of the gars when i kept my old one with them--
