[Ebook] The New Guide to Aquarium Fish – Brackish Water Fishes – The Asian Chromides

The New Guide to Aquarium Fish 0

Two species of cichlid are found almost exclusively in brackish water: Etroplus suratensis (Green chromide, 45 cm (18 in)) and Etroplus maculatus (Orange chromide, 10 cm (4 in)). Both occur in coastal regions of southern India and Sri Lanka, chiefly in brackish estuaries and lagoons. The salinity of both types of habitat is variable, depending on the state of the tide and the fresh water input, which varies with the seasons.

[Ebook] The New Guide to Aquarium Fish – Cyprinodonts – KILLIFISHES

The New Guide to Aquarium Fish 0

The egglaying Cyprinodonts have always been regarded as difficult because they are believed to require special conditions, namely soft acid water, but while this is true for some species it certainly isn’t the rule for all of them. Many are exceptionally colourful and this alone makes them good aquarium fishes, but to see them at their best requires dedication on the part of the aquarist. It takes a lot of time and patience to maintain banks of small species aquaria, remove eggs from spawning mops, or dry out peat and then raise the fry. For those of us who have kept killifishes the work involved is worth it. If you haven’t very much space, then try with a single species tank.

[Ebook] The New Guide to Aquarium Fish – Catfishes – Other Catfishes of General Interest

The New Guide to Aquarium Fish 0

With over 2000 species from which to choose, only a very small selection can be described here. Other species to look out for are Pimelodus pictus (Angelic Pirn), often sold as a community aquarium catfish, with a striking silvery body and black markings. This South American naked catfish grows to about 14 cm (5 1/2 in), and is fairly active during the day. Adult specimens may eat very small fishes, but juveniles are usually harmless. They can, like many catfishes, be extremely difficult to handle owing to their sharply pointed dorsal and pectoral fin spines. If these puncture your skin the mucus of the fish can cause mild blood poisoning, which can be quite painful for an hour or two.

[Ebook] The New Guide to Aquarium Fish – Catfishes – Doradids: The Talking Catfishes

The New Guide to Aquarium Fish 0

Doradids are usually called talking catfishes due to the noise they can make, but they are not the only catfishes to employ noise as a form of communication. Doradids achieve this in two main ways. One method is to stridulate the pectoral fin joint by partially locking it while moving the fin spine. This movement need not be great to make a lot of noise.

[Ebook] The New Guide to Aquarium Fish – Catfishes – The Banjos

The New Guide to Aquarium Fish 0

Dysichthys (Banjo cats) belong to the South American family Aspredinidae. They live in the leaf litter found in shallow forest waters, where their resemblance to dead leaves helps to conceal them. These small fishes (less than 12 cm) are often available to the aquarist, and are at home in the furnished aquarium, where they burrow into the substrate leaving just their eyes showing. Although rarely active, the sight of a few of them rising from the sandy substrate when food is offered is appealing.

[Ebook] The New Guide to Aquarium Fish – Catfishes – Loricariids: The Suckermouthed Catfishes

The New Guide to Aquarium Fish 0

The loricariids, from South America, are a most disparate family of catfishes, in both shape and size. All exhibit an underslung sucker mouth and most are herbivorous. The mouth is used to attach themselves to solid objects to avoid being carried away in the current, as they are particularly poor swimmers. The body is encased in body plates that develop from skin folds in the early fry stage, which in later life make swimming a difficult and laborious chore.

[Ebook] The New Guide to Aquarium Fish – Catfishes

The New Guide to Aquarium Fish 0

Garfishes are arguably the most diverse of all fishes, in body form, lifestyle, size, and distribution. There are over 2000 different species, principally from tropical freshwaters, but also from temperate climes and marine waters. Indeed, catfishes are to be found in every continent and ocean with the exception of the poles. With such diversity, only generalizations can be given in this brief introduction, but this same variety can also be the catalyst for a deeper interest on the part of the aquarist in this group of fishes.
