it is a shorty(pretty sure) and seems healthy. ull have to watch the deco. i dunno the back just seems to be a large hump if u will. it seems off. i dunno just something seems off. nice specimen, good to add more gar. hope ur ready to possibley lose it, as shortys are notorious for dieing even under perfect conditions. its what shortys do. and with as many gaps in ur deco u run a slightly higher risk. but it also may help it calm down. they are much much more skittish than other gar, die randomly with no rhyme or reason, stay much skinnyer, and seem to burn through more food(IMO). good luck and keep us updated
ps iv got a massive throbbing headache(and have for like 3 days) so i cant think, and am all over the place. hope i made since and am correct but i just cant think clearly
