Types Of Fish Tanks
Are you confused about what fish tank setup ideas you should go with? I sorted out some of them to help you. You may not know, but there are many types of fish tanks you can choose from.
If you are planning to buy one, and want some home aquarium ideas to start with, here are some best fish tank ideas for you.
Freshwater Fish Tank
If you have never had fish as pets before, I would suggest that you should explore freshwater tank ideas. Freshwater tanks are ideal for newbies as they are not costly, easy to maintain, and come in all sizes.
Beginners should start their freshwater tank setup with simple filtration and keep fish only. Once they get hold of it, they can also introduce other tank mates to their fish, like turtles or snails.
Saltwater Fish Tank
Going through saltwater fish tank ideas is just a waste of time if you’re on a budget. Saltwater fish tanks are the most deluxe fish tanks not everyone can have. They are very high maintenance, and even saltwater fish are very expensive and hard to find.
They require complex filtration systems that can be chemical, mechanical, or biological. A good filtration system is a must in saltwater tanks.
Also, it would help if you never bought a small saltwater tank as saltwater fish need a 20-gallon tank at least. Saltwater aquariums are costly but worth it.
Coldwater Marine Tank
Coldwater marine tanks are very challenging to maintain, and they are not for the weak-hearted people. They require powerful chillers to keep the water below room temperature all the time.
They also require insulators as the cold temperature causes a lot of condensation, and a sweating tank can make everything foggy. Marine aquarists have to invest a lot in Coldwater marine tanks, and this is not a hobby everyone can afford.
Coldwater Freshwater Tank
Coldwater freshwater tanks require much less maintenance as compared to coldwater marine tanks. They also hold fish at cold temperatures, but the difference is that they are for freshwater fish and cold water marine fish tanks are for saltwater fish.
Coldwater freshwater tanks are comparatively less expensive than marine ones, and filtration is also optional in these tanks.
Tropical Freshwater Tank
If you plan to pet tropical fish like guppies or catfish, you need a tropical freshwater tank. These tanks are not complicated to install and maintain, making them a good option for beginners.
Although they need all water filtration systems, which can be expensive, they are not that expensive.
Tropical Marine Tank
If you want to step up your game, you can get yourself a tropical marine tank. These tanks are super sturdy and hold rare tropical fish like the famous Nemo- the clownfish.
They are highly priced and require a lot of effort and maintenance. But once a tropical marine tank is set up, it is a treat to watch because of its bold colors.
You may get nervous before having a brackish water tank, but you shouldn’t be. It may sound tricky to handle at first, but it is not. If you know how to handle a freshwater aquarium, you will easily get hold of brackish tanks too.
Many aquarists recommend them as they are a safer option for fish. Many parasites and diseases die in brackish waters due to the salt content. You just have to keep a close eye on its pH levels as they need hard water.
Suppose you like taking on challenges and setting up a reef tank. Reef tanks are very colorful and vibrant, and they can cheer up anyone’s mood in a minute.
You can have all of the rare reef fish in your home once you set up this tank. They are the most challenging saltwater tanks you will ever come across. Be ready to spend a lot if you are getting one.
