Tetras are the most common type of fish found in South America after catfish. Their name is commonly used for a large group of fish characterised by the presence of a small adipose fin between their dorsal and caudal fin. The term Tetra is actually not a taxonomic grouping, as many unrelated fishes from differing families have been commonly called Tetras.
Tetras are the second most commonly kept fish in community tank setups, after livebearers (see our Livebearer Care Sheet for more information on these fish) . They are popular because of their vibrant colours, manageable size, mild behaviour and schooling habits.
Tetras range from 2 – 12cm depending on species. Longevity ranges from around 1 year for some small species to several years.
HOW TO INTRODUCE YOUR NEW FISH
- Always quarantine your new fish to observe health and behaviour prior to introduction to your main aquarium.
- Make sure you check your water quality in any aquarium before adding new fish. If it is not suitable then do a water change and check pH and GH. You can purchase an easy to use test kit to help you monitor these water parameters.
- Sit the unopened bag in the top of the tank and leave it for 5 to 10 minutes for the temperature to equalise.
- Open the bag and pour fish and water into a bucket. Slowly pour 1 cup of your tank water into the bucket. Repeat this process every 5 minutes until you have doubled the water volume in the bucket.
- After another 5 minutes take your fish from the bucket with a clean fish net and release into your aquarium. DO NOT use the water from the bucket – throw this water away.
- A prophylactic treatment of the tank with Melafix, De Stress and or a broad spectrum anti biotic treatment, can help fish overcome the stress of getting relocated which often can bring illness.
