The article in brief
The xipho fish, native to Central America, is a popular choice for aquarists. Here are the key points to remember:
- Features Marked sexual dimorphism, males with sword-shaped caudal fin
- Colours : Wide varietyfrom natural green to bright red and pearly white
- Maintenance Easy, ideal for beginners. Aquarium 120-200L for 6-10 individuals
- Reproduction Viviparous, prolific. 20-100 fry every 4-6 weeks
- Longevity 2 to 5 years with good care
Ah, the xipho fish ! What a magnificent aquatic creature that never ceases to amaze me. As a keen aquarist, I've been lucky enough to observe and breed many specimens over the years. Let me share with you my experience and knowledge of this little jewel of Central American freshwater.
Origins and characteristics of xipho
Xipho, from its scientific name Xiphophorus helleriiis a freshwater fish native to the tropical regions of Central America. It is mainly found in Mexico, Guatemala, Belize and Honduras. This colourful little fish has won the hearts of many aquarists, and with good reason!
What is fascinating about the xipho is its marked sexual dimorphism. Males are generally smaller (6-10 cm) and proudly display a sword-like extension of their caudal fin, hence their nickname "sword-holder". Females are slightly larger (8-12 cm) but lack this distinctive feature.
A funny anecdote: during my first experience with xiphos, I thought I'd only bought females. What a surprise when, a few weeks later, I saw these famous "swords" appearing in some individuals! That's when I realised that males can develop their secondary sexual characteristics late in life.
A rainbow of colours
One of the reasons for the xipho's popularity is undoubtedly its varied range of colours. In the wild, they are mainly found in green, but selective breeding has led to the development of many varieties:
- Bright red
- Pearly white
- Deep black
- Bright orange
- Sunshine yellow
This diversity of colours makes it possible to create truly spectacular aquariums. Personally, I'm partial to red xiphos, which add a touch of dynamism to any tank.
A fascinating viviparous fish
An exciting feature of the xipho is its viviparous (or more precisely ovoviviparous) mode of reproduction. The female incubates the eggs inside her body and gives birth to fry that are already formed. It's always a moving sight to witness the birth of these tiny, perfectly formed fish.
Maintenance and care of xipho in aquariums
Thinking of adding xiphos to your aquarium? Excellent idea! These fish are relatively easy to keep, making them an ideal choice for aquarium beginners. Here are a few tips on how to provide them with the best possible living conditions.
An adapted living space
Xiphos are active fish that like to swim in all levels of the aquarium. For a group of 6 to 10 individuals (the minimum recommended), you'll need an aquarium of at least 120 to 200 litres. Don't forget that these little swimmers can be real acrobats! I learned the hard way that a lid is essential to prevent them from running away.
Create a varied environment with aquatic plants, roots and rocks. Xiphos are particularly fond of planted areas that provide hiding places and resting places. In my aquarium, I've planted Vallisneria and Cryptocoryne which are perfect for reproducing their natural habitat.
Water parameters and maintenance
To ensure that your xiphos flourish, make sure you maintain stable water parameters:
| Parameter | Recommended value |
|---|---|
| Temperature | 21-28°C |
| pH | 7-8 |
| Hardness | 10-30°GH |
A weekly water change of 20 to 30% is generally sufficient to maintain good water quality. Don't forget to treat your tap water with a conditioner to remove chlorine and chloramines.
Balanced diet
Xiphos are omnivorous fish that are not very difficult to feed. Here is an example of the varied menu I offer them:
- Quality flakes for tropical fish (basic feed)
- Granules to enhance colours
- Frozen artemia (2-3 times a week)
- Live or frozen daphnia (1-2 times a week)
- Fresh vegetables such as blanched lettuce or spinach (occasionally)
Be careful not to overfeed them! Two or three small meals a day are more than enough. One thing I've learnt from experience: observe the behaviour of your fish and they'll tell you whether they're hungry or not.
Reproduction and cohabitation
If you want to start breeding xiphos, you should know that it's relatively easy. These fish are prolific and can give birth to 20-100 fry every 4-6 weeks. However, make sure you have a plan for the babies before you start!
To encourage reproduction, maintain a ratio of around 3 females to 1 male. This reduces stress for the females, who may be harassed by over-enthusiastic males. I've noticed that adding platy in the aquarium can create an interesting dynamic and reduce the pressure on xiphos females.
Beware, however: xiphos can hybridise with other Poeciliidae such as the guppys. If you want to preserve the purity of your bloodlines, avoid mixing them.
In terms of cohabitation, xiphos are generally peaceful and get on well with other non-aggressive species. They form a hierarchical society within their own group, which can make for some fascinating interactions to observe.
Health and longevity of xipho
With good care, xiphos can live between 2 and 5 years. However, like all fish, they can be prone to certain diseases. The most common is ichthyophthiriosis, also known as "white spot disease". Good water quality and a balanced diet are your best allies in preventing health problems.
One piece of advice I always give to novice aquarists is to keep a close eye on your fish every day. A change in behaviour or appearance can be an early sign of a health problem. The earlier you intervene, the better the chances of recovery.
Finally, the xipho is a captivating fish that will bring life and colour to your aquarium. Easy to keep, sociable and beautiful, it will delight beginners and experienced aquarists alike. So, are you ready to dive into the xipho adventure?
