Otocinclus Affinis

Nombre: Otocinclus, otocinclus enano, otocinclus dorado

Clasificación:

  • Orden: Siluriformes
  • Familia: Loricáridos
  • Genero: Otocinclus

Forma: La típica de los peces gatos, presentan la parte ventral aplastada, y la dorsal, tan ligeramente abombada, que apenas se percibe. Vistos desde arriba tienen forma de lágrima alargada.

Tienen la boca ínfera en forma de ventosa. La aleta dorsal tiene forma de abanico semiabierto y la caudal forma recortada. Posee aletas pectorales, pélvicas y ventrales; estas son transparentes, mientras que la dorsal y caudal tienen ligeros toques de color negro.

La parte superior es gris amarronada con reflejos dorados y el resto del cuerpo es blanco. Le atraviesa el cuerpo en sus laterales una línea negra que parte del morro, atravesando el ojo y terminando en la base de la aleta caudal haciéndose más estrecha al llegar a esta donde se convierte en una mancha en forma de punto.

Dimorfismo sexual:

Casi inapreciable, la hembra es ligeramente más grande y redondeada

Hábitat:

Río caquetá, Canca y Japurá (Colombia); Sureste de Brasil y Mato Groso. Se encuentran en ríos con corriente y con mucha vegetación

Tipo de acuario:

Especifico, comunitario o amazónico. Bien iluminado (para facilitar el crecimiento de algas) con abundante vegetación de cualquier tipo que se adapte a los parámetros del agua, aunque suelen preferir las plantas de hojas anchas. Dado que no son buenos nadadores no deben estar con peces agresivos que puedan dañarles. Tampoco con peces que tengan sus mismos hábitos alimenticios y puedan competir con ellos por la comida.

Son peces gregarios, se deben mantener en grupos, por lo que el tamaño del acuario debería ser de al menos 40 l. Son de hábitos nocturnos, durante el día suelen permanecer adheridos a las plantas, vidrios y diversa decoración del acuario. No se deben meter en acuarios nuevos, son peces que no se adaptan con facilidad, la calidad del agua tiene que ser optima para que no sufran. Si hay una subida de nitritos no podrán soportarla. Se debe ser muy escrupuloso con el acondicionamiento previo a la introducción al acuario, será básico para asegurar su correcta adaptación.

Es recomendable tener un buen filtro que provoque corrientes ya que son peces que gustan de ellas.

A diferencia de lo que se cree, no son grandes comedores de algas.

Tamaño:

Hasta 5 centímetros

Alimentación:

Se alimentan sobre todo de las algas verdes del acuario, aunque acepta otros tipos de alimentos preparados. No obstante no podría sobrevivir en acuarios que no tengan algas, por lo que debería agregarse a su dieta complementos vegetales (calabacín, pepino, lechuga…)

Temperatura:

(22.0-26.0) ºC

pH:

6.0-7.0

Dureza:

(5-14) ºGH

Sociabilidad:

Pacifico y gregario mantener preferiblemente 4 o 5 individuos a ser posible con mayor numero de hembras que de machos.

Reproducción: Difícil.Ovíparo.

Para incitar a la puesta, se les puede alimentar previamente con alimento vivo o congelado. Esta se realiza en grupo con más machos que hembras. Los machos persiguen a las hembras hasta que son aceptados. Las hembras ponen los huevos (pequeños y pegajosos) en las paredes del acuario o en las hojas de las plantas. La puesta no es muy abundante. La eclosión tiene lugar en los 2-3 días siguientes. Una vez realizada la puesta los padres se desentienden de la misma, por lo que los huevos pueden ser retirados a un acuario de cría con agua del acuario principal y con poca profundidad por ejemplo 3 a 5 cm añadiendo un oxigenador.

Las diminutas larvas deben ser alimentadas durante los primeros días con infusorios. Posteriormente, se irán añadiendo a su dieta nauplios de cyclops y artemia, y espinacas hervidas finamente trituradas (prestando especial atención a la limpieza del agua).

Expectativa de vida:

Hasta 10 años

  1. Apple now has Rhapsody as an app, which is a great start, but it is currently hampered by the inability to store locally on your iPod, and has a dismal 64kbps bit rate. If this changes, then it will somewhat negate this advantage for the Zune, but the 10 songs per month will still be a big plus in Zune Pass’ favor.

    I’ll gear this review to 2 types of people: current Zune owners who are considering an upgrade, and people trying to decide between a Zune and an iPod. (There are other players worth considering out there, like the Sony Walkman X, but I hope this gives you enough info to make an informed decision of the Zune vs players other than the iPod line as well.)

  3. This is getting a bit more subjective, but I much prefer the Zune Marketplace. The interface is colorful, has more flair, and some cool features like ‘Mixview’ that let you quickly see related albums, songs, or other users related to what you’re listening to. Clicking on one of those will center on that item, and another set of “neighbors” will come into view, allowing you to navigate around exploring by similar artists, songs, or users. Speaking of users, the Zune “Social” is also great fun, letting you find others with shared tastes and becoming friends with them. You then can listen to a playlist created based on an amalgamation of what all your friends are listening to, which is also enjoyable. Those concerned with privacy will be relieved to know you can prevent the public from seeing your personal listening habits if you so choose.

  4. Hands down, Apple’s app store wins by a mile. It’s a huge selection of all sorts of apps vs a rather sad selection of a handful for Zune. Microsoft has plans, especially in the realm of games, but I’m not sure I’d want to bet on the future if this aspect is important to you. The iPod is a much better choice in that case.

  5. Zune and iPod: Most people compare the Zune to the Touch, but after seeing how slim and surprisingly small and light it is, I consider it to be a rather unique hybrid that combines qualities of both the Touch and the Nano. It’s very colorful and lovely OLED screen is slightly smaller than the touch screen, but the player itself feels quite a bit smaller and lighter. It weighs about 2/3 as much, and is noticeably smaller in width and height, while being just a hair thicker.

  7. If you’re still on the fence: grab your favorite earphones, head down to a Best Buy and ask to plug them into a Zune then an iPod and see which one sounds better to you, and which interface makes you smile more. Then you’ll know which is right for you.

  8. Between me and my husband we’ve owned more MP3 players over the years than I can count, including Sansas, iRivers, iPods (classic & touch), the Ibiza Rhapsody, etc. But, the last few years I’ve settled down to one line of players. Why? Because I was happy to discover how well-designed and fun to use the underappreciated (and widely mocked) Zunes are.

  15. The Zune concentrates on being a Portable Media Player. Not a web browser. Not a game machine. Maybe in the future it’ll do even better in those areas, but for now it’s a fantastic way to organize and listen to your music and videos, and is without peer in that regard. The iPod’s strengths are its web browsing and apps. If those sound more compelling, perhaps it is your best choice.

  16. Sorry for the huge review, but I’m really loving the new Zune, and hope this, as well as the excellent reviews some other people have written, will help you decide if it’s the right choice for you.

    Claro que sí son muy buenos comedores de algas!!! Existen muchas variedades de algas y no todos comen de todas pero te aseguro que limpiaran tu acuario y más las algas marrones.
