Taking care of a freshwater aquarium fish
Your freshwater fish tank is the home of the fish living there. Hence, the environment should be healthy and clean at all times. As it is an enclosed space, you need some pointers to maintain it without any mishap.
Here, we have listed essential tips for taking care of the ecosystem in which the freshwater fish will be living.
- Understand the importance of the nitrogen cycle
Using an aquarium filter by letting the nitrogen cycle kick in within six weeks is an important step. This filter consists of three distinct elements: a mechanical element, a natural element, and even a chemical element.
All the produced substances from the fish’s left-over food and the decomposed waste need to be processed. The filter arrangement does this processing.
- Know when it is time to introduce your fish to its aquarium
We understand that you are excited to dip all the weird aquarium fish into the water. However, you can’t do it when you feel like it. There is a way of introducing the fish to the aquarium.
- Before you plunge into dipping the fish in the display tank, you need to switch off all lights.
- Don’t let your fish get suffocated. How can you do that? All you have to do is equalize the temperature of water in the tank. Once you have done it, you can open the bag’s mouth with the fish and keep it open to allow the passage of air that the fish desperately needs.
- Proceed on to determine the pH level of the water present in the aquarium and the bag containing the fish.
- Use a net to put the fish into the tank water delicately. When you do it, you need to get rid of or discard the water in the bag.
The bottom line is that you need to filter out the tank at least once every month. A bonus tip for you is that you should get rid of the dead leaves and algae accumulated over time.

Their scale can be of four colors – blue, purple, green, and black.
This species isn’t easy to deal with on a day to day basis. They don’t like sharing their space with some other species. Also, they love to dig. Hence, don’t put live plants into the tank.
Wolf Cichlids can adapt to their ecosystem easily. They also bond with their caretaker quickly. You will be able to take care of this species if you have had experience in the past. One more thing – their diet consists of bugs and bloodworms.

Their body color is a dark shade of brown. They can blend in with the plants because of the specks on the body.

They will survive better in a 150-gallon freshwater aquarium. The diet includes worms, chopped meat, etc. They might be shy when it comes to interacting with other freshwater fish species.
One downside of owning these fish is that they are more prone to various diseases. You have to clean the aquarium frequently to keep them as healthy as they can be.
