hey all, it's been a while since i've been on site...lots of gar work going on in the field and experiments. anyway, here is my opinion on the "rarity" ranking of the gars by the species first, from rarest to most common (this primarily refers to what is available in the trade in the United States) :
Cuban gar (rare in LFS, not available in wild)
tropical gar (rare in LFS, but more attainable than Cuban; not available in wild)
spotted gar (rare in LFS, attainable in wild, but not commonly sought after)
shortnose gar (uncommon but does show up in LFS, attainable in wild)
alligator gar (frequently in LFS, attainable in wild)
longnose gar (frequently in LFS, attainable in wild)
Florida gar (common in both LFS and wild - latter if you are in Florida)
including the morphs is sort of asinine as they are generally overpriced IMO. but the general trend goes like this (disregard species, we are just looking at genetic condition) :
albino (very rarely encountered)
xanthic "gold"
leucistic "white"
melanistic "black"
in terms of hybrids, it's also up for opinion and depends somewhat on availability...here is a ranking based on what we know thus far (and my opinions) :
croc III & II (former is seen in the wild, not in the hobby; latter likely exists in the wild, but hasn't been documented. only one conclusive specimen on record)
croc I (was original hybrid available in the hobby, not seen much any more)
shortnose x longnose (hard to diagnose, but does exist in the wild, possibly randomly in the hobby)
that's what i got so far--
