Pelvicachromis pulcher is a small west African cichlid inhabitant of forested waterways with low conductivity and an acidic pH found in eastern Benin, Nigeria and western Cameroon. Like most Pelvicachromis, P. pulcher is primarily a detritus feeder with the majority of their nutritional needs coming from decaying plant matter. P. pulcher is probably the most well established West African dwarf cichlid in the international aquarium hobby today.

Kraljeva plaščarica ima dve genetsko pogojeni obliki,rdečo in rumeno, pri čemer je slednje vedno dominantna nad rumeno. Razmnožuje se bodisi v monogamnih parih ali pa v haremu, pri čemer paru pomagajo satelitski samci (ki so vedno rumena oblika). Avtorji so hoteli ugotoviti, kake so razmerje med temi načini razmnoževanja, kak je uspeh mladic in so zato postavili ogromen biotop akvarij z plenilci mladic (P.taenitus in tetra Alestes sp.) in plenilcom mladic in odraslih osebkov (H. fasciatus). Kaj so ugotovili, pa preberite v tem zelo zanimivem članku.

THE HABITAT DESCRIPTIONS OF PELVICACHROMIS PULCHER (CAMEROON, NIGERIA) FOR A BIOTOPE LIKE SCAPING - with two video links and with two pics

Hi Davide! You asked about the possible habitats of Pelvicachromis pulcher

"Because of limited sources it’s easy to draw insufficient conclusions"

WHERE
Pelvicachromis pulcher comes from eastern parts of Benin, southern parts of Nigeria and from western parts of Cameroon, Ndonga area. Ndonga is the only area where P. pulcher is known to exist south of the country of Nigeria. The Ndonga population of P. pulcher is most likely a remnant from a time many thousands of years ago when the coastline between Cameroon and Nigeria extended much farther out into the Atlantic Ocean. It follows that the Ndonga population of P. pulcher looks very different from the well-known Nigerian.

HABITAT DESCRIPTIONS - WATER FLOW, BOTTOM COMPOSITION and PLANTS
I studied a few scientific researches regarding P. pulcher, but didn’t find from them any proper descriptions about the (many?) natural habitats of this species. From the available studies I have, I drew “a general” conclusion, that P. pulcher inhabits BOTH slow and fast-moving water. There is not much plant growth in the streams and rivers of Cameroon and Nigeria. Mostly there are Water lilies (Nymphaea), Crinum, Anubias on the edges of rivers but on the streams, it’s devoid of plant growth, with lots of rocks and dead leaves. Though there are some islands of plant growth but more made up of overhanging growth from shore based plants.

--- I made one tiny mistake in my previous answer > A DESCRIPTION FROM NIGERIA. This habitat description by Ted Judy wasn’t from Nigeria; it’s from Cameroon, Ndonga area: "The stream (in Ndonga) we collected in is broad and shallow, with a sand and gravel bottom punctuated by sporadic larger rocks. THE CENTER OF THE STREAM flows faster than the edges, and it is this difference in flow that scours sediment from the middle of the stream and deposits it along the sides, resulting in the middle of the stream being rockier than the edges. The shoreline is somewhat muddy and has dense growths of MARGINAL plants. THE ONLY TRULY AQUATIC PLANTS we saw in the area were some Nymphaea water lilies."
--- Ted Judy continues: “Locating the P. pulcher was frustrating. We first concentrated on the DENSELY VEGETATED areas along the SHORELINE using a large seine, but only captured a few juvenile specimens - According to Nwadiaro (1985; in Anton Lamboj’s book “The Cichlid Fishes of Western Africa”) smaller specimens are found in the upper parts of the Sombreiro River in Niger delta area while larger ones are found in the lower regions. Nwadiaro suggested that smaller specimens prefer the upper and shallower regions because they offer more protection against predators common to deeper waters - We eventually found adult fish holding small territories around the bases of the larger rocks in the center of the stream, which is NOT the classic Pelvicachromis habitat in which MOST species are found.”
--- Nathan Hill’s description about the habitat of P. pulcher is similar to that of Ted Judy: “The fluviatile habitats of P. pulcher can be also QUITE FAST FLOWING, water running past between 10-50 cm/second. Such a flow affects the environment that the fish live in, so in this case the presence of fine leaf litter or mulm, which is where Kribs live, is sometimes reduced. INSTEAD, RIVERBANKS tend to be TEEMING WITH PLANT LIFE, and the only debris found is large and heavy with smaller pieces being washed away. ROUNDED STONES and HEAVY BRANCHES are what a wild P. pulcher would recognize in its habitat, along with a CLUTTER-FREE substrate of fine and coarse sand, and occasional larger leaves.”

HOME BIOTOPE
1) A moderate flowing biotope: Marginal shoreline vegetation (Anubias spp.); moderate water flow in the middle away from the marginal vegetation; the bottom composed of sand, gravel and sporadic larger stones (with possible Nymphaea growth) > that’s it! In natural environments of P. pulcher there are not many different plant species in one locality. African fern, BOLBITIS HEUDELOTII in the habitats of P. pulcher; not known.

2) Or alternatively a slower moving stream section > In Anton Lamboj’s book there is a pic about a small creek in Cameroon, where P. pulcher is found. This creek seemed to have quite slow water flow with overhanging growth from shore based plants. No other accurate habitat descriptions were available.

VIDEOS - WORTH WATCHING smile emoticon
The video link "Pelvicachromis, an den Ufern des Ndonga - Unterwegs in Kamerun" follows below. In this video you can see a habitat of P. pulcher in Cameroon (Ndonga area) - faster water flow and the bottom composition.
Also about the second video (VERY VERY diversified), “Fishman Cameroon Wholesaler of West African Cichlids and Plants” the link follows below smile emoticon It's made by the West African cichlid expert Michel Keijman. In the beginning of this video – beautiful underwater sceneries for INSPIRATIONS - you can see how Crinum natans and Anubias sp. grows on the bottom in flowing water, and in time 7:45 > 9:14 how Nymphaea sp. covers some areas on the bottom.

--- Anyway, now you have some basic knowledge for your future master work! There surely exists more available material about the habitats (also pics) of this species. Michel Keijman has published many articles about the genus Pelvicachromis, but unfortunately I don’t manage Dutch language! Please, try to contact by email Anton Lamboj and Michel Keijman.

--- In the first pic the distribution of the Genus Pelvicachromis smile emoticon Kind regards!

Kraljevska plaščarica, Pelvicachromis pulcher, Boulenger, 1901



Slika je iz strani: http://www.akvariumas.lt

Druga imena: "kribensis"

Družina: Cichlidae (Ostrižniki)
Izvor: Nigerija
Velikost odraslega primerka: 7-10 cm
Odnos do drugih rib: teritorialna in agresivna v času parjenja, drugače miroljubna riba.
Razlika med spoloma: v mladosti jih je težko ločiti, odrasla samica je manjša, ima zaokroženo hrbtno in repno plavut (samec ima koničasti), samica ima bolj čokato zaokroženo telo, samec pa je bolj podolgovat, samice so tudi nekoliko bolj barvitejše
Pretežno zadrževanje v akvariju: dno, sredina akvarija
Ureditev akvarija: dobro zaraščen akvarij z veliko skrivališči
Minimalen volumen akvarija: 60l
Hrana: brez težav sprejme vse vrste žive in pripravljene hrane
Oskrba: ne težavna, ker je trdoživa riba, ne zahteva posebnih parametrov vode
PH: 6,5 do 7,5
Trdota: mehka do trda voda
Temperatura: 24 – 27° C
Voda: je rečna riba, zato naj bo voda čista
Naravno okolje: Pogozdene vodne poti z manjšim pretokom in kislim pH-jem.

Kraljevske plaščarice so ostrižniki, ki tvorijo pare in ko je par osnovan, se bosta zlahka parila tudi v akvariju naseljenem z ostalimi ribami. Vse kar ta parček potrebuje je votlina, ker se ne pari na odprtem, v nasprotju z nekaterimi drugimi ostrižniki. Prevrnjeni cvetlični lonček, kup lesa (korenine), kup skalovja, lupina kokosa ali navadna PVC cev, tvorijo dobra skrivališča za parjenje. Če uporabite lupino kokosa, jo temeljito očistite in naredite majhno vstopno odprtino za vhod oz. izhod. Če sestavljate sklop skal, poskrbite za trdnost, da se ta ne sesede, ker ob pripravi skrivališča parček izmenično odstranjuje pesek iz votline. Za vezavo kamnov ali skal lahko uporabite tudi primeren silikon. pH vode ima najvažnejši vpliv na spol potomcev. Če je voda bolj alkalna (višji pH) bodo potomci pretežno moškega spola, ob kisli vodi (nižji pH) bodo potomci večinoma ženske, nevtralni pH pa zagotavlja večjo uravnoteženost spola pri mladicah. Samica običajno prva začne dvorjenje. V primeru, da imamo v akvariju več samcev, se bo parila z najmočnejšim razpoložljivim samčkom v skupini. Samcu bo pokazala njen živordeč trebuh, se pred njim zvijala in izvajala hitre tresljaje s svojim telesom. Ko jo samec sprejme, ji odgovori na enak način. Nato samička odloži od 50- 300 iker na notranjo stran izbrane in pripravljene votline, samec jih nato oplodi. Plaščarice so dobri starši. Samička čuva ikre in kasneje mladice, samček pa medtem brani teritorij. V tem času postanejo posebno agresivni in odganjajo celo ribe, ki so precej večje od njih. Če opazite, da se ostale ribe zadržujejo v kotih akvarija, je to dober znak, da sta se ribi sparili. Je pa pomembno imeti ostale ribe v akvariju, ker to povzroča večjo skrbnost novih staršev, v nasprotnem primeru lahko svojo agresivnost preneseta drug na drugega. Dobre vzporedne ribe za tak akvarij so hitri plavalci, kot so na primer tetre, nekatere mrenice...Ikre se razvijajo 3-8 dni. Starši ikre lahko v svoji skrbi prenašajo na druga mesta z nošenjem v ustih. Mladice splavajo po 5-10 dneh. Če je akvarij uležan, je v njem dovolj hrane za mladice. Ko mladice splavajo, jih lako hranimo z zdrobljenimi luskami in solinskimi rakci. Pri hranjenju pomagajo tudi starši, s pljuvanjem hrane proti mladicam. Starši zbirajo mladice v skupino in jih vodijo v "šolo" in "na ekskurzije" po akvariju. Včasih hoče eden od staršev prevzeti sam skrb nad mladicami in napada partnerja ter ga odganja. Če se to zgodi, morate drugega partnerja odstraniti, preden se pobijeta ali poškodujeta. Če je možno, ne premikajte mladic izven akvarija, dokler starša nista pripravljena na ponovno parjenje. Prezgodnja odstranitev mladic iz akvarija lahko povzroči nasilje med staršema, ponavadi je samec pripravljen na parjenje, samica pa še ne. V skupinskem akvariju jih družite z drugimi manjšimi ostrižniki ali ribami podobne velikosti. Niso pa primerni gupiji in ostale dolgoplavute ter počasi plavajoče ribe. Za manjše akvarije velja, da se je potrebno izogibati naselitvi skupaj z ribami, ki se zadržujejo pretežno v spodnjem delu akvarija v izogib borbam za prostor. Akvarij naj bo zaraščen z rastlinami in naj ima veliko skrivališč. Plaščarice je dobro imeti z ostalimi ribami, ki se ne skrivajo in plavajo na odprtem, ker se drugače večinoma zadržuje v zavetju skrivališč. So priporočljivi za začetnike, ljubitelje ostrižnikov. Včasih radi ščipajo rastline, zato jim lahko ponudimo poparjeno špinačo. Kraljevske plaščarice je užitek opazovati. Menjajo obarvanost v trenutku, posebno če jih hranite z nečim, kar imajo radi. Način kako plavajo, je tudi očarljiv. So hitri plavalci in se lahko nenadoma popolnoma ustavijo, plavajo vzratno in se celo premikajo bočno. Ob spopadanju in zapeljevanju razširijo plavuti, da so videti večji. Čeprav so majne ribe, so lahko tudi agresivne, zato je potrebno skrbno izbrati njihove sostanovalce. Njihova življenska doba je približno pet let.

Parček kraljevskih plaščaric imam tudi sam v akvariju, očarale so me že pred leti, sploh ker mi je z njimi uspelo vzgojiti že nekaj rodov, njihova skrb za zarod, način plavanja, barvitost in način parjenja...

Kraljevska plaščarica spada v družino ostrižnikov (Chiclidae) in ni najbolj miroljubna riba, predvsem v času drsti in kasneje, ko skrbi za zarod, močno preganja vsako drugo ribo. Včasih je priporočljivo imeti v akvariju še kakšno ribo, ki jo bo parček seveda precej preganjal, vendar tako preprečimo, da bi se pričel parček "prepirati" in preganjati. Prav tako v nekaterih primerih zato bolje skrbita za zarod. V akvariju z več ribami obstaja možnost, da se ne bodo drstile. Parček skrbi za svoj zarod dokler mladice ne zrastejo. Če želimo, da se par hitreje prične ponovno drstiti odstranimo mlade ribe iz akvarija (po približno 5 tednih). Zarod je lahko dokaj velik: 20-60 mladic.
Hrani se z vsemi vrstami hrane: od suhe listnate, tubifexi, artemije, tekne jim tudi hrana za diskuse, z velikim veseljem pospravijo tudi nastrgano telečje srce (brez kit) in seveda se vse ostale vrste žive hrane.
V akvariju je pomembno imeti dovolj skrivališč, podlaga pa naj bo bolj droben pesek. Ko si parček izbere kraj, kjer se bo drstil, bo med peskom in skrivališčem izkopal v pesek luknjo in skoraj popolnoma zaprl vhod, potrebno je paziti, da kamne postavljamo dovolj trdno, da se, tudi ko bo pod njimi luknja, ne prevržejo ali porušijo na ribe.
