In genere fotografare un acquario non è proprio facile, anche per chi ha una buona attrezzatura e n...e capisce di fotografia. Tuttavia si può ottenere una buona foto anche con uno smartphone e qualche accorgimento fotografici di base!!
Quali? Ve lo sveliamo ora!
Devin Biggs is back with a look at Nigel Toby's resplendent #riparium #aquarium; it's inspiration for every #aquascaper, above and below the water. See more of this amazing #plantedtank at https://www.reef2rainforest.com/…/the-celestial-swamp-a-ri…/
#novataxa #Amazon #biodiversity #fish #neotropic #Ichthyology • 2018 :: #Pseudacanthicus major • A #NewSpecies from #rioTocantins Basin, Brazil: One of the Larg...est Known #Loricariidae (Hypostominae: Ancistrini)
Abstract :: The genus Pseudacanthicus currently comprises the following six species distributed in the Amazon and #Tocantins basins, and coastal drainages from #Guyana to #FrenchGuyana: P. #serratus, P. #fordii, P. #histrix, P. #spinosus, P. #leopardus, P. #pitanga, and P. #pirarara. Herein we describe Pseudacanthicus #major, from rio #TocantinsBasin, one of the largest loricariid species known. The new species is distinguished from its congeners by the following combination of characters: having body color pattern with dark brown background without spots or blotches and dorsal and caudal fins with transversal white bands; anterior process of compound pterotic with no contacting with the posterior margin of the orbit and by the absence of a conspicuous crest on the posterior edge of parieto-supraocciptal. Other osteological characteristics are further used to diagnose P. major from others congeners. A discussion on #gigantism and miniaturization in #freshwater fish, ornamental fisheries activities, threats and conservation of the new species are also provided. || #Pisces #Amazonia #fishtrade #taxonomy #conservation #Hypostominae #Ancistrini #Amazonia #SouthAMERICA
We received from #Indonesia once more a nice shipment containing pretty #Sicyopus #gobies. These gobies are - despite the external similarit...y - not feeding on #Aufwuchs and microfilm like #Stiphodon and #Sicyopterus, but are little predators that feed on quite large food items. These include also very small #fish and #shrimps up to a length of about 1 cm, although the gobies become only 5-6 cm long and are very slender fish.
In respect of the #determination there appeared at lot of trouble. Initially the fish were totally colourless and we thought they would belong to the species Sicyopus #zosterophorum (Bleeker 1856); but then many males obtained full coloration and were pretty sure that the fish are S. #exillisquamulus Watson & Kottelat 1994 - or at least almost sure. For in the latest scientific #literature the species S. exillisquamulus has been considered to be a synonym of Sicyopus #auxilimentus Watson & Kottelat 1994.
Finally Laurent Tyty kindly gave us the crucial hint that according to the most current scientific #literature (Keith et al., 2015) our fish is actually S. #rubicundus Keith, Hadiaty, Busson & Hubert, 2014; S. auxilimentus (besides S. exillisquamulus an additional synonym is, fide Keith et al., S. #cebuensis Chen & Shao, 1998) has in contrast to S. rubicundus no orange lips.
Our first importation of S. rubicundus dates back to the year 2006. At that time we termed them Sicyopus sp. Red. The species is distinguished from S. zosterophorum by the lack of a black stripe under the eye, bright orange lips and the lack of clearly visible vertical stripes. Moreover the basic coloration of S. rubicundus is rather orange and in S. zosterophorum red. The females of both species are almost colorless.
Sicyopus are inhabitants of #brooks and like clear, clean, and running #water, hiding places and sandy #bottom. Sicyopus regulary spawn in aquaria, they are cave brooders, but the #larvae are very tiny and develop in #marine #environements. We have not heard so far from a successful rearing of the larvae under hobby conditions.

Love is in the air! The Bluemask Darter, Etheostoma akatulo is one of our more spectacular darters. Here the female (on left) even shows some of the blue throat... coloring when spawning. We have at least three species of darters spawning now that water temperatures in our systems have reached the mid to upper 50s(F). This is just a quick cell phone picture and it really doesn't do them justice!

One of the beautiful sites we visited. This part of the Ebulle River (Cameroon) form a lagoon with crystal clear water. Can see in the same place, Chromidotilpia linkei, Chromidotilapia guntheri, Benitochromis flinleyi, Coptodon sp. and many other beautiful fish. Enjoy in HD

Il relitto del Thistlegorm: tra storia e natura - Dall’inferno del seconda guerra mondiale al paradiso dei subacquei.
Scientists in the Galápagos discovered a natural breeding site for scalloped hammerhead sharks—good news for an endangered species that they are working to track.
As some of you know, I am currently in the middle of my nearly annual winter trip to the Florida springs. This year, my number one target was the Bluenose Shine...r, a fish I have been trying to photograph for five years. Most of those attempts ending without me even finding them. They are a somewhat rare fish to begin with, and needing to find them in clear water adds another level of difficulty for me. Several years ago I did get to snorkel with them in a clear Florida spring, but for multiple reasons (including low light levels and kids jumping in the spring and ruining the visibility), I did not end up with any satisfactory photos. Thankfully, my luck finally changed this year. It feels good to have finally gotten an image that comes close to doing this species justice.
