Before you actually go out and purchase the most beautiful fish you can get your money on. You will first need to decide if you want:-

Each type of aquarium has it’s own benefits and species of fish unique to the water temperature of your tank. Generally, heated aquariums offer more varieties of fish to choose from.

Cold Water Freshwater Aquarium

A cold water aquarium keeps the water at room temperature. You should still include a filtration system. Additionally you should have a light for the tank. These help promote health in your fish.

If you’ve decided on keeping a cold water fish tank, here are some ideas for beginners.

1. Gold Fish

1GoldfishGold fish come in many varieties of sizes and colors. Many people love the fancier varieties with bubbly heads and fanned tails.

Gold fish are great for beginners who have an unheated aquarium. These fish prefer temperatures between 62-74 degrees Fahrenheit.

Gold fish tend to be messy eaters. So, be sure to change 10 percent of the water each week.

Treating the water with a dechlorinator is also a good idea.

Some aquarists prefer to use heated tanks simply because of the varieties that it offers. A heated tank allows you to keep a wider variety of tropical fish. The temperature typically ranges from 72 to 82 degrees Fahrenheit.

Here are seven easy care freshwater aquarium fish for those who decided on a heated tank.

1. Danios

DaniosThese small fish are a great first fish. When first starting up a tank, you need to test the water.

Because these fish are hardy and do well in a variety of conditions, they are a perfect first choice.

Danios are active and small. Typically, they prefer to be in a group near the surface of the water.

Most have bright horizontal stripes that grab your attention as they zoom around the top.

They are not picky eaters and do well with flake fish food.

2. Black Molly

Black Molly The black molly is a peaceful fish. It is a good choice if you want a community tank with several types of fish.

One of the advantages of choosing this fish is that it can adapt to fresh, brackish and even salt water. This allows you some leeway when setting up a new tank.

These fish prefer a temperature that ranges from 70 to 82 degrees Fahrenheit.

They are livebearers, so if you buy a male and a female pair, you could end up with babies. However, they do tend to eat the young if there is not adequate vegetation for the babies to hide in.

Platies

Paties are great for beginners because there are so many varieties to choose from. They do

very well in a community tank with other passive fish. As a livebearer they will produce young frequently. Most often the babies are eaten by other tank members.

Platies are selectively bred to create new combinations of colors. You will be sure to find several that suit your taste.

They will eat any flake or freeze-dried food. They are also a good choice because they eat any algae that might develop in the tank.

The males, though, have a long bottom fin that looks like a sword. These are passive fish that will add bright color to your tank.

They are hardy and long lasting fish, which makes it perfect for beginners.

With a variety of colors to choose from, you will be sure to want one, or several in your tank.

    Dear Dennis,
    White Cloud Mountain Minnows
    I have kept these fish outdoors(I live in Berkeley, CA.). So it rarely goes below 32 F. However, one year, I had a school in an Oak barrel and the temperature drop into the teens for three days around Christmas. The surface froze to a thickness of 2-3″ of ice. At the same time, a client of mine had the exact conditions but her water feature was even smaller than my barrel, which also iced over. I kissed those fish goodbye! I only saw a few fish after the thaw but I was amazed! Then some time in March, I saw numerous fish and a huge number of fry. The “tropical fish” store where I purchased these fish will just not believe my observations. They keep telling me 65F is the minimum. White Clouds are much more hardy than that and should be used in more outdoor situations. “EASY”

    Dennis,

    I would have to say guppies!
    When I just a boy, old enough to have my first tank, my dad started me on guppies; inexpensive, quite hardy, easy breeders… before I knew it I had three tanks going and was working on breeding my own fancy combos.
    don’t think you could go wrong with guppies :)
    I have raising and breeding a variety of fresh water fish ever since. It’s a great hobby!

    Hye dennis,
    Just this morning, I have bought a kind of molly (species unknown)and mixed it with the gold fish. Unfortunately, it got bitten severely by the bigger goldfish… is this normal I mean goldfish should be a peaceful fish right?

  4. Reply mr cat Dec 3,2013 2:59 pm

    Owh yes, I more question, can fish grow their fin and tail back? Just curious… ;)

    • Reply Dennis H. Dec 7,2013 8:33 pm

      Theoretically Molly and Goldfishes are not compatible with each other. There living conditions are different. Goldfish are coldwater fish while Mollies (being a tropical fish) needs a heated tank. Mollies are brackish, meaning a mix of freshwater and saltwater. Goldfish may not survive well in brackish water. Still many keep them together, which bring us to your question. So only advice I can give you is, please do not keep them together.

      Molly got beaten as of now, but once the goldfish is full grown they will be eating most of the tropical fish small enough to fit into the goldfish’s mouth

      Most fish can grow their fins back, however you need to provide optimal conditions to encourage re growth.

    I really liked the article. I’m actually shocked not to see corys not make the list. Most supposed experts sware by them as great beginner fish.

    Dennis –
    Just like to throw out a suggestion – be very careful mixing goldfish with most other fish. They produce a large amount of ammonia thru their waste, and many other fish will not be able to tolerate those levels. I have great goldfish in an outside small pond and keep a 70 gal. heated aquarium for others. Just a warning before it’s too late – speaking from experience here.

    What about neon tetras?

    • Reply Kathy Feb 27,2014 3:34 pm

      Ivan, I have been keeping Neon tetras since I started fishkeeping 5 years ago (these were my first fish) and I find them very easy to care for. (Some might disagree.) My 40 tank is mostly tetra varieties – Diamond Tetras, Black Skirt Tetras, Neon Tetras, Glowlight Tetras. I also keep Celestial Pearl Danios and a couple of Otocinculus for algae control. I’ve made sure to plant plenty of hideaway places for the Black Skirts and Danios. So far, everyone seems to get along and I often see some of the Danios schooling with the Neons. Of course, maintaining good water conditions is also very key. Good luck!

    Hi there. I have a 60lt tank which is cold water. In there I have 2 common goldfish about 2 inch big, 2 small plecs ( cant remember what type they are but the shop info says it grows to 5 cm) and 4 shrimp. Can I have other coldwater fish in there? The shop I got the shrimp and plecs from said I cant because the goldfish will eat smaller fish but if im correct the other coldwater fish I can have grow to about the same size as the plecs. So why can I have the plecs but nothing else?? Any info thanks.

    My 5 year old wants a “school” of “tiny” fish that don’t grow. We currently have one goldfish that we love in another tank so I’m in the process of setting up a new tank in her room for her new friends. Given that I’m the one taking care of them I want them to be EASY. Already I’m in over my head cycling a tank (which I had to look up on the internet). Can you recommend anything that would be a good choice? I have the fluval 2.5 gallon and a heater so it can be a heated situation, but it’s small.

    Ina,
    Probably too much ammonia. Gold Fish produce a lot of waste, so filter or change a % of the water weekly.

    Hello-
    I’m relatively new to aquariums. I currently have 4 platies and 1 pleco in a 20 gallon tank. The platies seem to have reached a point where no more breeding is occurring (no babies that survived to adults in the past 8 months). I’d like to know if it would be ok for me to get 1 betta and a few swordtails (all males or all females; I’ve had enough with babies for a while).
    Thank you!

I thought they were meant to be nice natured….. What should I do. I tried putting him with my fighter but that wasn’t much better.

    Mollies are one of few fish that can go fresh, brackish, and completely salt.

    Hi! I have a fantail goldfish, a spotty goldfish, a sucking loach and a small fish (species unknown). My 2 fan tails go to the top of the tank all night to blow bubbles, I would like to know if this is normal, also the goldfish are always together (nudging each other ) could they possibly be having fry? If so I have a anemone kind of plant, could they breed in it? Thanks Great Page!

    I had 5 Kuhli Loach, that survived for a number of years till a black out for a couple of days, They survived though so much, my tank cracked an most died but because they lived under the gravel, I then got a massive oscar and it would eat everything except them, they just hid to well. They also become larger then I thought (3 foot tank) and they dont each much. This was when I first started till 2 years ago, Ive always wanted more.
