Making the right choice of fish
The choice of fish is very important – as is the shop where you buy them. There are thousands of species, but if you’re a beginner at fish-keeping, we advise you to choose species that are easy to rear, inexpensive, and highly compatible together.
YOUR CHOICE SHOULD BE GUIDED BY THE FOLLOWING CRITERIA:
- The quality of water chosen: cold water / warm water, fresh water / sea water. Avoid diverse mixes of fish at all costs: for instance, don’t mix goldfish (cold-water) with tropical fish (warm-water).
- Aquarium size: the fish need living space proportionally to their size. For their comfort, avoid large species in smaller aquariums (less than 100 litres). Prior to any purchase, check the size of certain species of fish which are sold young but may reach 30 cm when adult and be unsuitable for your aquarium. This is particularly the case for cold-water fish, e.g. koi carp.
- Ease of care, bearing in mind your experience and the requirements of certain varieties: beginners should choose species that are easy to care for and inexpensive. More experienced fish-keepers may choose more demanding species that are rarer but also more expensive, e.g. discus fish.Compatibility of species; take particular care with aggressive species, which it’s difficult for smaller fish to live alongside:
- avoid keeping widow rockfish and brill with small fish;
- gouramis and angelfish can cohabit but they will not tolerate fish that are smaller than them;
- African cichlids need to be kept in specific tanks: they cannot live alongside other species, and also require a particular biotope (mineral decor with no aquatic plants);
- You’ll have far fewer problems with species compatibility for cold-water fish than with warm-water fish. However, if you add large fish, take care that other fish in the same species don’t nibble their fins.
Don’t forget that the quantity and choice of your fish should be in direct proportion to your experience and the size of your aquarium. Just as a large volume of water will be a lot more stable in terms of biological balance and require less maintenance, mistakes in the choice of fish (in terms of species and quantity) will be less harmful in a large aquarium than in a small aquarium.
