Triggerfish
« on: 29 December, 2012, 13:08:58 »
Triggerfish su ribe iz porodice Balistidae, i ima ih oko 40 vrsta.
Naseljavaju tropske i subtropske okeane, sa navecim sadrzajem ovih riba u Indo-Pacifiku.
Obicno se mogu naci u priobalnom podruciju a pogotovo na koralnim grebenima, sto je sjajna prilika za biotopski koralni greben u morskom akvarijumu.
Neke od vrsta mogu narasti i do 60cm, dok ima vrsta koje dosezu do 30cm. U zavisnosti od litraze akvarijuma i prostora, mogu dostici do 12cm u manjem zatvorenom sistemu.
Imaju jaku vilicu i zube koji im pomazu da bez problema polome kucice puzeva i skoljke, mada se takodje hrane i sitnijim ribama, kozicama i rakovima.
Shodno ovome, proteinska hrana bazirana na pomenutim organizmima je preporucljiva pri drzanju ove ribe u akvarijumu.
Parametri vode i temperatura su identicni osnovnom sistemu koralnog akvarijuma ili "fish only" akvarijumskog sistema.
Moje zapazanje se odnosi na povoljni uticaj ove ribe u akvarijumskim uslovima, koji se ogleda u tome sto riba u potrazi za hranom prikuplja delove detritusa iz "mrtvih uglova" vodene struje, i ispusta ih u vodu kroz skrge, na koji nacin sprecava nagomilavanje detritusa u akvarijumu na nepristupacnim mestima.

Triggerfish je dobio naziv po svom karakteristicnom ledjnom i grudnom peraju, koje je rigidno kada je ispravljeno.
Ovi "triggeri" mu sluze da ih ispruzi i time "zakljuca" sebe u procepu stene kako bi izbegao da bude izvucen napolje od strane ribe koja ga napada.
Takodje postoji sjajna zanimljivost vezana za ovu ribu i cinjenicu da aktivno ispusta zvukove.
Zvuke ispusta na tri nacina. Trenjem zuba, trenjem unutrasnjeg dela ledjnog peraja uz kicmeni stub, vibracionim udaranjem pektoralnih peraja uz strane tela, t.j. uz vazdusni mehur.
Iz prve ruke sam slusao razlicite zvuke koje ispusta i zaista zvuci zadivljujuce i iznenadjujuce glasno.
Cim utvrdim koji zvuk je povezan sa kojom akcijom ili raspolozenjem, pisacu opsirnije o tome u ovoj temi.

Triggerfish je poznat po svojoj izuzetnoj inteligenciji, i cinjenici da zaista moze biti pravi ljubimac u vasem akvarijumu.
Prepoznaje kada mu prilazite sa hranom, aktivno utice na odnos sa vasom rukom koja je u akvarijumu. Premesta elemente u akvarijumu ako ih pomerite i "gurka" vas ako mu smetate.
Potrebno je naglasiti da je Triggerfish izuzetno teritorijalan pa je pozeljno obratiti paznju sa kojim ribama se nalazi u istom akvarijumu.
Ima tendenciju da bude agresivan prema ribama koje ga okruzuju u cilju ocuvanja teritorije. Ne retko tera i gricka ronioce u prirodi ako se isuvise priblize mestu na kome se mresti.
Mrest u akvarijumu jos uvek nije izveden, iako se strucnjaci aktivno trude kako bi rasteretili izlov ove divne ribe zbog potreba akvarista.
Primerci ove ribe su prilicno dostupni, a ja sam mog ljubimca nasao u ReefrooM-u.

Evo kratkog "dokumentarca" o ovim ribama i fotografijama koje ilustruju profil ove jedinstvene ribe:

Izuzetno nepovoljan po LPS i meke korale jer ih zatrpava peskom koji filtrira kroz svoje otvore...

Sjajna riba, ceo svoj aklvarijum sam preuredjivao, vadio pesak i jos svasta samo da ga ne bih morao izbacivati  :)

Za one koje zanima da malo bolje upoznaju ovu jedinstvenu ribu, evo samo jednog odlomka iz "Sound Production and Associated Behavior in Triggerfishes" od strane Michael Salmona, Howard E. Winna i Nina Sorgentea.
Ovaj odlomak iskljucivo samo govori o ponasanju ove porodice riba i povezanosti zvukova koje ispustaju u skladu sa datim situacijama.


"Behavior Associated with Sound Production

All species but B. eapistratus were observed
in the field. When approached by a diver, about
half the fish swam away rapidly. Other fish
showed quite different behavior. They
swam in irregular paths, sometimes in wide
circles, and then stopped by a hole or ledge in
the reef. When again approached, the fish might
leave the area and continue swimming until and pull it from the area, a rapid burst of sound
another hole was found . Eventually, each fish was produced. The sounds could sometimes be
entered a hole and extended its dorsal and elicited by directing water currents into the area.
ventral spines against the walls of the space. No sounds were heard until currents were proWhen attempts were made to grasp the fish duced or until grasping attempts were made.
Escape behavior of Rhinecanthus rectangulus when chased by a diver.
All fish stopped producing sounds a few seconds after attempts to dislodge them ceased. If
pulled from the area, the fish continued to produce sounds until released. These observations
are based upon the behavior of over 60 R. rectangulus, and at least 15 fish in the remaining
species (excluding B. eapistratus).
Most fish in the field were widely spaced,
although in Meliehthys sp. occasionally some
were seen swimming in groups. In Balistes and
Rbinecantbus, individual fish swam alone near
the bottom, with only 5-10% of the fishes remaining near a hole or ledge in the coral for
brief periods (5-30 minutes) . On one occasion, 17 B. bursa were seen feeding on a small
area of coral. Several large fish briefly chased
smaller conspecifics away from the area, then
return ed to feed. The chasing was accompanied
by a slight opening of the mouth and rapid,
continuous volleys of pectoral fin drumming
sounds. In two other cases, quite different behavior was observed during sound production.
One fish approached anoth er which had been
hovering near a hole for several minutes. The
"resident" and the "intruder" then slowly circled, simultaneously rising about 1-2 m off the
bottom. Brief volleys of pectoral fin sounds were
produced by both fish as they circled. In addition, the body coloration of both changed from
the usual tan to a bright yellow. The intruding
fish then swam away from the area. Brief chasing between conspecific R. reetangulus was also
observed, but no sounds were detected.
On two separate occasions, individual B.18
vetula near coral ledges in Bimini were observed
to chase approaching conspecifics from the area.
The aggressive fish changed in body coloration
from a light to a dark brown, while the opercular area became bright yellow. Pectoral fin
drumming sounds were produced by one of the
aggressive fish during chasing.
Many pectoral fin sounds were produced by
B. vetula and M. piceus in the fish pen at Bimini. In three hours of recordings, sounds were
produced at least once a minute. However, the
large number of fish present made impossible
the identification of the individuals involved.
On four occasions, loud sounds were correlated
with rapid chasing of one M. piceus by another
across the length of the pen. In most recordings,
presumably of sounds from both species, several
sounds were produced in a series for up to a
9-second period. In a few cases, the sounds
consisted of a single, loud burst.
Individuals of M. piceus in the circular concrete tank remained in the shelters for several
days and only occasionally ventured into the
open central area. This behavior was not comparable with that of conspecific fish in the pen
or the field, and so only B. vetula was used for
further observations. These fish adapted to the
tank very quickly, i.e., they accepted food (fresh
conch), produced sounds, and swam about the
whole area within one hour after populations
were established.
The most intense aggressive behavior occurred
within the first 2-3 hours after the fish were
placed in the tank. One fish in each of the two
groups was dominant over all others. Chasing,
sometimes accompanied by pectoral fin sounds,
characterized the behavior of all aggressive fish.
Submissive fish, usually smaller individuals,
were dark or light brown in color. Most aggressive fish usually had bright yellow opercula.
A total of 134 aggressive interactions were
observed, consisting of chasing of a conspecific
by an aggressive fish. In 44 observations, the
aggressive fish produced sounds by pectoral fin
drumming just before or during the chase.
Sounds were also produced during other less
frequent interactions, i.e., when two fish circled
slowly around one another for a few seconds
(sounds produced by both fish in three observations); when one fish, after producing sounds,
displaced a second fish from a shelter (12 obPACIFIC SCIENCE, Vol. XXII, January 1968
servations) ; and when resident fish inside their
shelters produced sounds in response to intruding fish (12 observations)."

Tacno znam o cemu govoris, i evo morao sam zbog njega malo da promenim i pojacam vodenu struju.
Obzirom da mi je podloga bez peska, dize se samo detritus, a sa dobro planiranim vodenim strujanjem sam resio i ovo.
Sad sve funkcionise perfektno uz blagu adaptaciju zbog ove ribe. Ono sto mi je najbitnije je da uopste ne dira korale, a hranu za nju imam u skoro svakoj samoposluzi (totalni Low-Budget). :)

Evo kako izgleda Triggerfish kod mene u Low-Budget-u dok klopa:

Ma on je vec drugi dan poceo da jede iz ruke, Trigger je to a ne akvarijumska riba. ;)

Vlado, hranim je odmrznutom lignjom i odmrznutim gamborima iz Maxi-ja, mada komotno moze da jede i hranu u listicima slicnog sastava.
Idalje Low-Budget funkcionise sjajno kao sto vidis, i citava bioloska filtracija se bazira iskljucivo na zivom kamenu i mekim koralima.
Doduse, jednom nedeljno "usisam" dno i vratim tu istu vodu nazad kroz levak napunjen perlon vatom kako bih uklonio detritus.
Ovde komotno moze alternativno da se ubaci i bilo koji motorni filter samo sa perlon vatom, ali da se vata menja na svakih 3-4 dana, kako ne bi doslo do prikupljanja nezeljnih materija u vati.

Temu o Low-Budgetu najbolje da nastavimo ovde:
