Otocinclus

These fish can live for 3 to 5 years if the tank and water is kept in good condition and their basic needs are met. Like any animal, poor care and living in a stressful environment can significantly impact their life expectancy.

Most varieties of Otocinclus are small with adults rarely growing more than 2 inches in size. This size makes them one of the most popular freshwater nano fish out there.

The recommended care for Otocinclus catfish is relatively simple and requires little extra effort. This is part of what makes them so appealing to tank owners, they’re super low-maintenance!

In general, these fish spend a lot of time near the bottom of the tank since this is where the algae tends to be. They are also adaptable and can withstand changes in their environment better than other fish of their smaller size.

They’re also very docile and get along with almost any other freshwater aquarium species. This means they’re unlikely to get themselves into trouble in your tank. In the wild, these fish travel and live in schools which helps them stay safe as well.

In their native South American habitats, these fish often attach themselves to rocks, gravel and other river bottom surfaces that contain algae growth. They tend to graze on algae and often stay in groups to better protect themselves from larger fish.

Here are the water parameters you want to aim for:

• Water temperature: This should be maintained at a warmer 72°F to 79°F.
• pH levels: This should be kept neutral in a range of 6.8 to 7.5
• Water hardness: These fish do well in soft water with readings no greater than 15dH for best results.
