What Fish is Easy to Care for
Have you been thinking of taking up fishkeeping as a hobby? Perhaps you just bought your first aquarium, and are looking for the easiest low-maintenance fish to take care of?
From beginners to novices alike, everyone appreciates fish that have a greater ability to thrive under a variety of different water conditions. While every fishkeeping enthusiast strives to ensure that water conditions remain as close to ideal as possible, the reality is fluctuations happen from time to time.
Having low-maintenance, hardy fish can set you up for success, as it maximizes your chances of having a tank full of happy, thriving fish. Read on to learn more about our top picks!
What is a Beginner-Friendly Fish?
While individual circumstances may vary, beginners tend to do best when they select fish that are hardy and able to withstand occasional mistakes made as part of the learning curve.
Replicating natural water conditions can be challenging for even seasoned fishkeepers, and beginners are likely to find this extra-challenging. Thus, it is important to pick species that can tolerate a wider range of water conditions, and adapt to different environments.
Another key feature of beginner-friendly fish is a peaceful temperament. Beginners gravitate towards community tanks as they provide greater variety and interest, which is why they need to select fish that can get along with their tankmates.
Fish with gentle demeanors do well in community tanks as they are not territorial and will not fight for dominance. This is definitely a key factor to consider in selecting beginner-friendly fish.
Tips That Every Beginner Fishkeeper Should Know
Being a beginner to fishkeeping can be overwhelming, as it is a hobby that requires a significant amount of technical knowledge, time, and homework. However, the intellectual challenge is part and parcel of what draws hobbyists to fishkeeping.
As you embark upon this journey, here are a few tips to bear in mind:
Don't Always Trust Your Local Fish Store Staff
When you're starting out, it can be tempting to turn to your local fish store staff for guidance on which fish you should pick.
Unfortunately, fish store employees usually make recommendations based on what's available in-store, rather than naming species that would be best for your needs. As you would expect, stores typically carry fish requiring different levels of care.
Left at the mercy of the fish store's inventory, you may end up choosing fish based on availability rather than suitability. This may cause you to end up with fish with highly specialized needs.
Therefore, the best approach is to do your research prior to approaching fish stores. Make sure you have a clear idea of what you're looking for!
Never Forget To Cycle a New Aquarium
Cycling a new aquarium sets you up for success, as it ensures that your tank contains all the helpful bacteria it needs to maintain optimal nitrite and ammonia levels. This is essential to the health of your fish.
It can be tempting to skip aquarium cycling as a beginner, as it is a process that takes multiple weeks. However, your patience will eventually pay off in the form of nitrifying bacteria that will help you build your dream aquarium.
While there are multiple ways to cycle an aquarium, people typically cycle their aquariums with hardy fish or with aquatic plants. The former allows you to keep hardy species of fish in your aquarium from Day 1, while the latter involves creating a gorgeous aquascape. A win either way!
Smaller Tanks are Not Easier To Keep Healthy
We've touched briefly on the importance of cycling an aquarium, but size is yet another factor that has a significant impact on the quality of your water.
Simply put, smaller tanks are more prone to overcrowding and overfeeding, which can lead to excess ammonia and nitrification in the water. This is extremely dangerous, as it can lead to the sickness or even death of your fish.
Larger ones are easier to keep healthy. For that reason, we recommend making a decision sized appropriately for the number of fish you own.
