Enneacanthus gloriosus

The Bluespotted Sunfish (Enneacanthus gloriosus) is a coldwater fish and a real oldtimer among aquarium fish. Aquarists used to name the up to 7.5 cm long fish "working class discus", due to its brillant colours and the nice behaviour. However, it was never as expensive as the discus.

Bluespotted Sunfish occur in nature along the southeastern coastal region of the US. Here they live in ponds and slow moving rivers with clear water and a dense vegetation. In the aquarium they are not undemanding. They need clean, clear and preferably soft and slightly acidic water. Moreover they are said to be very anxious and can die when shocked. Neverless it is not a big problem to fulfill these demands and a tank with Bluespotted Sunfish belongs to the most beautiful looks one can have in the whole aquarium hobby.

Like all sunfish, the Bluespotted Sunfish usually refuses flake food, it is better to feed them on frozen and live food The term "coldwater fish" is often misunderstood. In this case it does not mean that the tank for sunfish has to be cooled in living rooms. These species have no problem with temperatures as high as 26°C for some time. However, they need a cool period during winter at 4-10°C, otherwise they will not breed. In Central Europe this species will not survive extreme winters in the garden pond, so it is better to bring them in a cool cellar room from December to March.

For our customers: the fish has code 803803 on our stocklist. Please note that we exclusively supply the wholesale trade.  Lexicon: Enneacanthus: ancient Greek, means "with nine spines". This refers to the structure of the dorsal fin. gloriosus: Latin, means "glorious". Common name: Blue spotted sunfish

Lepomis gibbosus

The Pumpkinseed (Lepomis gibbosus) is one of the most beautiful coldwater fishes. Moreover it has a very interesting behaviour. The species originates from central parts of the North American continent. The continental climate (hot summers, cold winters) makes the Pumpkinseed a hardy fish and so it was transferred by humans to many regions as a foodfish. To Europe it was brought around 1880 for the first time. Since then it became a native fish in Europe but was not able to settle over the whole continent. Nowadays the Pumpkinseed is blamed as an unwanted and useless species in Europe.

In its natural habitat the fish grows up to 25 cm, but in Europe it stays small. How come? Indigenous North American populations of the Pumpkinseed serve as food fish for many predators. The strategy of the Pumpkinseed is a a very high reproduction rate. In Europe these predators are missing what leads to a mass-reproduction and the fish stay dwarfish. This phenomenon is also known from other fish species. The perch (Perca fluviatilis) also becomes dwarfish where predators are missing. And so the Pumpkinseed usually grows only up to 5-10 cm in Europe.

In aquaria the fish can become much older than in nature. Like all fish the Pumpkinseed can grow its whole live through and so aquarium specimens can grow to a captial size. In the garden pond, on the other hand, they usually stay small (around 15 cm). With growing age the adaptability to changes in the enviroment lessenes and so most Pumpkinseeds die at the age of around 5 years due to weatherchanges or something similiar. It is wise to buy small individuals (4-5 cm) as their adaptability is high and they easily adopt to live in the new environment.

The garden pond for Pumpkinseeds should contain shallow parts with fine sand. Good growth of submerged plants is also important for the fish. Clear and clean water ist preferred. Pumpkinseed are small preators which feed on insect larvae, amphibian larvae, small fish and so on. They can be fed easily with frozen bloodworm, but will almost ever refuse dried food.

Males become bigger than the females and are more colourful. A pairbinding is not known in the species, the male will readily mate with any females that will come around. The males defend territories where they take care of the brood until the fry swims free.

Centrarchus macropterus

The Flier was a very popular aquarium fish some decades ago; nowadays it is somewhat "out of fashion". This is very unjustified, as is shown by the wonderful, 8-12 cm long specimens we currently have in stock. Fliers are calm, majestic fishes that are real eyecatchers for every well planted coldwater aquarium. In the garden pond, these fishes also look extremely beautiful when they stand in shallow water over sandy ground and the sun makes them glitter as if they were powered with gold dust.Young specimens show a well defined ocellus in the soft part of the dorsal fin which gets lost when the fish gorow to adult ages.For our customers: the fish have code 803106 on our stocklist.

For the first time ever we were able to import a specimen of this top rarity from the Venezolean Rio Ventuari! There are photos in the internet referring to the fish under the name of "Leporinus autana"; however, there is no described species of Leporinus that bears that name. In all probability L. sp. Ventuari represents a colour morph of L. brunneus.

In any case it is a breathtaking beautiful fish! For our customers: the animal has code 265974 on our stocklist. Please note that we exclusively supply the wholesale trade.

Priapella olmecae Blue-Eye

For the first time ever we have this beautiful livebearer in stock. The genus Priapella currently comprises 6 described species, of which P. intermedia and P. compressa are found occasionally in the ornamental fish trade. All Priapella species are surface dwellers that live in the wild in comparatively strong current. Here they swim in swarms, head against the current and jump for small insects that form the biggest part of their natural diet. The blue eyes of all species are very conspicuous. They shine so brightly that one is reminded of the lampeyes of the genus Aplocheilichthys.

Keeping these nice fish in a home aquarium is not difficult at all. However, they should be always kept in groups. The fish are very peaceful. The tank should be well lightened and filtered, the water temperature should be between 21 and 26°C. Medium hard to hard water and a pH over 7.5 is preferred. Priapella olmecae feeds readily on any usual food for ornamental fish, but never from the bottom. Plants are not harmed by this species.


For our customers: the fish have code 444513 on our stocklist. Available in limited numbers only! Please note that we exclusively supply the wholesale trade.
Lexicon: Priapella: means "tiny penis", referring to the male‘s gonopodium. intermedia: means "in between". compressa: means " compressed". olmecae: refers to the indigenous people in Mexico, the Olmecs. Aplocheilichthys: means "fish that is similar to Aplocheilus"; Aplocheilus is another genus of fish.

The gardenpond season starts up! The Tench, a species initially native in Europe and western Asia, is a perfect pond and aquarium fish. Nowadays the Tench has a worldwide distribution, because it is a very delicious food fish, too. The Tench is very tolerant regarding the water temperature: it is totally winter hardy on the one hand and has no problems at all in summer, when the temperature rises up to 26°C on the other. Due to its low oxygen requirement the Tench inhabits muddy waters in the wild.

Currently we have two sports of the Tench in stock, the wild coloured - also called Green Tench - and the wonderful golden sport. Among the latter ones are many three-coloured specimens, which are very rare (not assorted available!). The Tench can reach a length of about 40 cm (the largest one reported had 70 cm). Our specimens are currently 8-10 cm long and thus fit also perfectly for coldwater aquaria.

The Tench is not only a beautiful fish, but also very useful. Among all fish species native in Europe the Tench is spezialized most in feeding on small molluscs. Thus the Tench can be used in any pond or tank where snails become to numerous. However, in the absence of snails the Tench also feeds readily on any usual type of fish food. Against other fish, may they belong to the own species or not, the Tench is completely peaceful. Males can be distinguished from the females by the shape of the ventral fins, which are much larger in males. The Tench is an egg-scatterer that does not take care for its eggs at all.

For our customers: the Tench has code 878802, the Golden Tench 879003 on our stocklist. Please note that we exclusively supply the wholesale trade.

Lexicon: Tinca: this name was already in use in ancient Rome for the Tench.

Common names: Tench or Green Tench (for the wild coloured sport), Golden Tench (for the golden or threecoloured sports)
