Ang '''guno'''<ref name=JETE>{{cite-JETE|Guno, ''silverside fish''}}</ref> o '''''Atheriniformes''''' ([[wikang Ingles|Ingles]]: ''silverside fish'') ay isang [[order (biology)|orden]] ng mga isdang may mga [[palikpik]] na [[ray-finned fish|kahugis ng mga sinag]] na kinabibilangan ng [[Atherinidae]] o mga [[Old World silversides|guno ng Matandang Mundo]] at ilang mga pamilyang di-gaanong kilala, katulad ng pambihirang [[Phallostethidae]].
 
==Paglalarawan==
<!----------------------------
Karaniwang may dalawang panlikod na palikpik ang mga kasapi ng ordeng ito, may naibabaluktot na mga matutulis na mga tinik ang una, at isang palikpik sa puwitan na may isang palikpik sa harapan. Karaniwang malabo o wala ang mga [[linyang lateral]] (pahigang mahabang linya mula sa harap patungong likod ng isda).<ref name="Nelson"/> May magkakatulad na ilang mga katangian ang mga larba ng Atheriniform; mayroon itong pambihirang kaiklin ng haba ng mga bituka, mayroong isang hanay ng mga [[melanophore|melanopor]] sa kahabaan ng likod, at hindi agad mapapansin ang sinag ng mga palikpik hanggang sa ilang panahon matapos lumabas sa itlog.<ref name="Nelson"/>
==Description==
Members of the order usually have two [[dorsal fin]]s, the first with flexible spines, and an [[anal fin]] with one spine at the front. The [[lateral line]] is typically weak or absent.<ref name="Nelson"/> Atheriniform larvae share several characteristics; the gut is unusually short, there is a single row of [[melanophore]]s along the back, and the fin rays do not become evident until some time after hatching.<ref name="Nelson"/>

Nelson, 2006, the family [[Melanotaeniidae]] includes the subfamilies Bedotiinae, Melanotaeniinae, Pseudomugilinae, and Telmatherininae, to demonstrate their [[monophyly]].<ref name="Nelson">{{cite book|title=[[Fishes of the World]]|last=Nelson|first=Joseph S.|publisher=[[John Wiley & Sons]], Inc|year=2006|isbn=0-471-25031-7}}</ref> However, in a 2004 study, a different classification scheme classifies the families Bedotiidae, Melanotaeniidae, and Pseudomugilidae (also include Telmatherinine genera) in a suborder Melanotaenioidei.<ref name="Sparks2004">{{cite journal|url=http://research.amnh.org/scicomp/pdfs/Sparks_Smith2004b.pdf|title=Phylogeny and biogeography of the Malagasy and Australasian rainbowfishes (Teleostei: Melanotaenioidei): Gondwanan vicariance and evolution in freshwater|first=John S.|last=Sparks|coauthors=Smith, W.
