[March 05, 2025]   You love the mesmerizing, calming, smooth movements of watching a fish tank. You see lots of tanks in doctor offices' reception areas, certain restaurants, and zoos that have all sizes of beautiful underwater creatures.

So you think you want a fish tank? You’ll need to ask yourself do you want a saltwater tank, with lots of little Nemo’s, corals, seahorses, starfish, and/or anemones, or a freshwater tank where you can have many different beautiful live plants with fun snails, and shrimp? What does this all entail, how long, and most importantly, how expensive?

Whether you are planning a saltwater tank or a freshwater tank, there are several things that you need to prepare for and plan ahead of time. Here are some questions to ask yourself to help determine if a fish tank is a good choice and which type is best for your lifestyle.

Hopefully by now, if you are serious about purchasing a fish tank, you have done loads of research on the many different types of aquariums and the types of fish you are interested in keeping. Before purchasing a tank this decision will have to be made because although many things are similar between the two types of tanks, many are not. Your trusted aquarist will be of help to narrow down the size of the tank you need based on your area at home, the kind of fish you want, and how you want the tank presentation to be.

Be prepared to answer some of the following questions if wanting an aquarist to help determine the size and type of tank you will need:

Location, Location, Location

Once you set it up and fill your tank with water it will be exceedingly difficult to move it, so be diligent in how much room you have, your placement, and how much room surrounding it. For example, a 30-gallon fish tank full of water weighs approximately 348 lbs. and that is without the lighted lid, filters, heaters, décor, and fish. This is one of the most important steps. The location you choose should be decided upon very carefully. You will want to pick a place that gives you plenty of room with enough space to work and clean the tank. Hopefully, the main purpose of having this tank is to enjoy the whimsical fish and view the tank. Therefore, pick a place that fits the tank well while not letting it get in the way or in a location where it could get bumped into or tripped over.

Some new hobbyists will try to cut corners with equipment, but each piece is really necessary for a tank, especially a hood with LED lights. The hood will protect your fish from getting things accidentally dropped into the tank, hands and animals going fishing, will keep fish from jumping out of the tank (yes, this can really happen) and the light in the hood will allow a calming effect in the evenings for viewing.



• Also, keep in mind that the tank placement needs to be away from direct sunlight, direct cold drafts, heat/cold air ducts, and near a GFI outlet or waterproof surge protector. If you have a great expense in the tank with expensive fish, it would be wise to consider a backup plan for electricity as tanks cannot survive very long without the air pump for oxygen and a thermometer to keep the temperature at an acceptable level.

• You’ll also want to place this tank in an area where you can drain and fill the tank as needed without carrying water long distances. Cleaning out, exchanging water, cleaning, or changing filters or rock is a messy business and you want to be close to a sink, if possible, to cut down on the spillage. You will also need to place your tank at least half a foot from the wall to accommodate the filter you choose.

• If you decide not to purchase a fish tank/stand combo, then you will need to place the tank on a sturdy heavy table with four solid legs. Most tank/cabinet combos are built to be a smooth transition, by standing higher than a normal table and making for the best viewing options. Keep this in mind, because the height of the tank will deter other animals and kids from getting curious.

Where do I go, what kind do I get?

• Some larger pet stores will have good deals on many different-sized fish tanks with the cabinets and all the tools you need to get you set up, so the guessing (other than what kind of fish you want) has been decided for you such as what size filter for the size of tank, heater, light hood, media, rack, rock/sand. Watch out for those deals because they are usually at a much lower price than buying each part separately.

• Search for the closest pet store that has a large selection of aquatics available. If you live in a small population, chances are you will have to travel to a larger city to find one of these pet stores. Choosing a store where you feel welcome and comfortable should be a major consideration since you will have lots of questions and will rely on the staff to guide you, evaluate your water, and help with tank issues during the set-up and continuous monitoring throughout the life of your tank.

• Determining how big a tank that you need depends on what kind of fish and how many you want. If you are more interested in a salt-water tank, you typically need at least a 30-gallon tank to start, because there are too many water fluctuations in a smaller tank which leads to making it more difficult for the tank to grow a stable ecosystem.

Whereas with a freshwater tank, you can go much smaller. An aquarist can help you with the size and number of fish so that your new fish do not get stressed out and die prematurely. This is your fish’s home, it needs to be spacious, clean, happy, and safe.

• Think of any changes or additions you may want to make in the future so that you can plan ahead and make sure you have the space needed for this accommodation.

Saltwater Tank vs. Freshwater tank

Setting up any type of fish tank takes planning, but building a salt-water tank takes much more time and patience. It takes several weeks to get the tank set up and acclimated. Filling a fish tank is usually the same process for both types of tanks and each type has different chemicals (marine salt for salt-water tanks) to add to your tap water to get it to the proper stability for the fish, and for removing waste. You will also need to invest in a hydrometer to measure the water’s salinity and specific gravity and for a saltwater tank a saltwater test kit that should be used weekly in assessing the water levels. However, remember to research your specific fish because there could be additional requirements for the chemicals or temperature of the water.

Freshwater tanks are relatively less expensive because you can have a successful smaller tank such as a 10-gallon tank with a hood, filter, and gravel for around $50-$100, with most fish costing between $5-$40 each. Smaller freshwater tanks are not very time-consuming since most freshwater fish are hardier and are a little less stringent about having precise measurements in regards to chemicals. If new to the aquarium world, it might be good to start out with a smaller freshwater tank and gradually add to it as your interest and hobby grows.

Saltwater tanks of course do not require a different tank, it just should be at least 30 gallons for the best results. What makes the saltwater tank more expensive and time-consuming are the preparations for the exact water stability, temperature, and fish. The cost for most saltwater fish runs greater than $50 per fish and requires more chemicals and/or special lighting. Adding corals or live rocks inhabited by natural algae and bacteria can add another layer to monitoring the stability of the tank and can add to the overall cost. The time spent maintaining a saltwater tank has also greatly increased. The temperature of the water and the levels in the water need to be monitored on a daily basis in the beginning and at least weekly thereafter. Fish have a temperature range to survive in and the water levels, especially the ammonia and the pH. need to be tested. With a little practice, this can be done in the comfort of your own home, but it is suggested to take a sample of your tank water into your trusted aquarist for weekly testing (at least the first few months) where they can advise you what chemicals to add or purchase to get your levels into proper range. Typically, this testing is free of charge but check with your aquarist first.

Once your tank is put together, and levels are acceptable for your fish, according to your aquarist, please, please follow your aquarist’s suggestion in introducing your fish to your tank. Most individuals get so excited at this point that they just dump the fish in hoping that this is the last step to a fruitful fish tank. However, this is where most fish do not survive. Fish come from another fish tank, where more than likely they will use different chemicals, lighting, and water that differs from yours, so as not to shock your new fish system with a different water content or temperature, you must let the fish gradually get introduced to your tank or they will perish. This takes patience and time and if you follow your aquarist's suggested methods, then you will soon have a beautiful, bright fish tank that you can show off to friends and kids alike.
