About Caridina

Caridina

caridina — "Garnele, Krebs & Co." (shrimp, crab & co.) — is the German specialist magazine for the invertebrates in the freshwater aquarium, published quarterly by the Dähne Verlag in Ettlingen. "Das einzigartige Magazin über Wirbellose im Süßwasseraquarium" (the unique magazine about invertebrates in the freshwater aquarium): where the fish usually take center stage, caridina covers all the other aquarium animals — the shrimp, the crabs, the crayfish, and the snails. Four times a year, it delivers everything worth knowing about successful keeping, breeding, and care — for interested beginners as well as experienced breeders. The ISSN 1863-2696 marks the bibliographic identity.

Overview

The magazine serves the invertebrate aquarists: the shrimp keepers, the crab enthusiasts, the snail collectors, and the nano-aquarium fans. The editorial program answers the hobby's central questions: How do I keep the animals? With what can I socialize them? What do they eat? What technology do I need? Which water plants can I use? — the questions the specialist retail, faced with the abundance of newly imported species, is often not yet equipped to answer. The traditional aquarium journals leave too little room for the invertebrates: caridina does it better.

The focus areas — alongside the animals — include the aquarium technology (lighting, filtration, heating, measurement and control), the nano-aquaria, the aquarium setup, the water plants, the feeds, and the decoration materials. The quarterly rhythm — four issues a year at 9 euros per copy, 35 euros annual subscription domestically — serves the dedicated hobby: the deep, practical, well-illustrated reading. The publisher's media data lists the four caridina issues as the invertebrate complement to the sister magazine aquaristik (six issues a year, 12,500 readers, some 6,900 subscribers).

History

The Dähne Verlag — Am Erlengraben 8, 76275 Ettlingen — has published the aquaristic specialist press: the aquaristik magazine (six times a year, the attractive and practical magazine for all active hobby aquarists, interested beginners, and the zoological specialist retail's staff) and the caridina quarterly as the invertebrate specialist. The shrimp boom — the Caridina and Neocaridina species' rise in the aquarium hobby, the bee shrimp's Crystal Red breeding, the Sulawesi species' discovery — gave the magazine its subject: the invertebrates moving from the bycatch to the main attraction.

The editorial — Oliver Mengedoht (redaktion) — and the publishing contacts — Thomas von der Heyde, Thomas Heinen (advertising) — carry the title: the Ettlingen aquaristic publishing house. The media data — the joint aquaristik/caridina rate card — documents the current advertising business: the four caridina issues bookable alongside the aquaristik. The standalone website's current unavailability notwithstanding, the print magazine continues within the publisher's program.

Coverage and Content

The editorial program follows the invertebrate keeper's year. The shrimp boom — the magazine's biological context — deserves its telling. The Caridina genus — the freshwater shrimp's most diverse group, from the bee shrimp (Caridina logemanni, described 2014 by Klotz & von Rintelen) to the tiger shrimp (Caridina mariae) to the cardinal shrimp (Caridina dennerli, described 2009 from Sulawesi's ancient lakes) — conquered the aquarium hobby: the Crystal Red's 1996 Japanese breeding, the high-breeding lines' genetics, the Sulawesi endemics' colors. The Amano shrimp (Caridina multidentata) — the algae eater — became the aquascaper's tool. The trade's challenge — the commercial names not always matching the actual species (the green dwarf shrimp's unclear status) — needs the magazine's taxonomy: the scientists (Klotz, von Rintelen, Karge) describing the species, the journal translating the systematics for the keepers. The book — Karge & Klotz's "Süßwassergarnelen aus aller Welt" (Dähne Verlag, Ettlingen 2007) — is the publisher's reference: the shrimp bible. The crab and crayfish coverage — the dwarf crayfish, the crabs — addresses the larger invertebrates: the tanks, the socialization, the escapes. The snail coverage — the ornamental snails — completes the invertebrate spectrum.

The nano-aquarium — the magazine's technical context — deserves its telling. The nano tanks — the 10-to-60-liter aquaria — made the invertebrates' keeping accessible: the small volumes, the desktop formats, the complete sets. The technology — the LED lighting, the nano filters, the heaters, the measurement and control (the pH, the conductivity, the temperature) — stabilizes the small water: the shrimp's sensitivity demanding the precision. The aquascaping — the planted layouts, the stones, the roots — turns the nano tank into the living art: the shrimp grazing the moss, the snails cleaning the glass. The water plants — the mosses, the Anubias, the Bucephalandra — are the invertebrate tank's infrastructure: the hiding, the grazing, the water quality. The feeds — the specialty shrimp foods, the minerals, the leaves — complete the care: the nutrition science for the tiny crustaceans. The setup coverage — the aquascaping, the plants, the decoration — serves the aesthetics: the invertebrate tank as the living picture. The feed coverage — the specialty foods — addresses the nutrition: the shrimp foods, the minerals. The breeding culture — the hobby's advanced level — deserves its telling. The high-breeding — the Crystal Red's grades, the Taiwan bees, the fancy tigers — is the shrimp hobby's sport: the genetics, the selection, the culling — the lines refined over the generations. The water parameters — the soft water, the low pH, the active soils — are the Caridina keeper's science: the bee shrimp's demands versus the Neocaridina's tolerance. The Sulawesi species — the cardinal shrimp's Lake Matano (pH over 8) — need the biotope fidelity: the ancient lakes' conditions recreated. The crab and crayfish breeding — the dwarf crayfish's offspring — extends the reproduction: the invertebrates' full life cycles in the tank. The magazine's breeding coverage — the successful keeping, breeding, and care for beginners and experienced breeders — gives the knowledge: the parameters, the techniques, the genetics — the invertebrate hobby's science, quarterly.

Organization and Ownership

caridina is published by the Dähne Verlag GmbH, Am Erlengraben 8, 76275 Ettlingen (Postfach 10 02 50, 76256 Ettlingen), telephone 07243/575-150. The editorial contact is Oliver Mengedoht; the publishing contacts are Thomas von der Heyde and Thomas Heinen (advertising, 07243/575-110). The Dähne Verlag — the Ettlingen aquaristic publisher — deserves its institutional telling. The publishing house — Am Erlengraben 8, 76275 Ettlingen, in the Baden town near Karlsruhe — serves the freshwater aquaristic: the aquaristik magazine (six times a year, the attractive and practical magazine for all active hobby aquarists, interested beginners, and the zoological specialist retail's staff — more than 12,500 readers, around 6,900 subscribers) and the caridina quarterly (the invertebrate specialty). The book program — Karge & Klotz's "Süßwassergarnelen aus aller Welt" (2007) — extends the journals: the reference works. The media data — the joint rate card — sells the combination: the aquaristik's six issues plus the caridina's four, the complete freshwater-aquaristic reach. The contacts — the 07243/575 exchange, the anzeigen@daehne.de advertising — serve the industry: the aquarium manufacturers, the specialist retail, the importers.

The business model follows the consumer-press pattern: the subscriptions (35 euros domestic, 40 abroad annually), the single-copy sales (9 euros), the advertising (the aquarium industry, the specialist retail), and the trial subscriptions. Detailed circulation figures are not publicly confirmed.

Digital Presence

The brand's digital home has been caridina.de (currently not live as a standalone site; the row's domain); the publisher's daehne.de carries the media data and the program. The Facebook presence — facebook.com/aquaristik.caridina — serves the community. The media data PDF — the joint aquaristik/caridina rate card — documents the advertising offers. The digital strategy follows the specialist-press logic: the print quarterly for the deep invertebrate coverage — the species, the technology, the breeding — the publisher's channels for the program and the community.

As the freshwater aquarium's invertebrate magazine — the unique title for shrimp, crabs, crayfish, and snails, published by the Dähne Verlag — caridina remains the invertebrate aquarists' quarterly companion: the keeping, the breeding, and the care — four times a year in print.
