This species doesn't need a lot of care, and it's a peaceful fish that likes to hide from sight. It grows up to 3 inches and requires a tank of at least 20 gallons.


You've probably seen tangs in most saltwater aquariums everywhere. These are bright yellow fish with an attitude. Tangs are very aggressive towards other tangs, and they tend to fight each other until only one is left. However, they’re effortless to manage and friendly to other fish species.

They need a 100-gallon tank to have enough room to swim around. Even though most tangs are yellow, they come in many different sizes and colors. No matter your choice, they will look fantastic in your saltwater aquarium.

Watchman Goby

The watchman goby should be high on your list of species. To begin with, it eats pretty much any kind of food and is easy to find in any pet store. They are popular because they do well with other species of fish, and they look pretty cool too. If you want to get more than one, make sure to keep them in separate tanks, or they will fight each other to death.

Chalk Bass

Chalk bass is a small, peaceful fish species from the Serranidae family.

They like to do their own thing and run to cover for safety. Damselfish come in many different colors, most of which can keep you glued to the aquarium for hours.

Coral Beauty or Flame Angelfish

There are many angelfish species, but the coral beauty and the flame angel are tied as one of the easiest to care for. The colors of these fish are amazing. The coral beauty has a deep blue body and head and yellow highlights that can sometimes appear orange. The flame angel has an orange body that seems to glow at times with dark stripes.

I see the question of putting an aquarium in a bedroom so many times, with so many different points of view. I grew up with an aquarium in my bedroom for my entire teenage years so I have a few tips.

Are you looking for something a bit different to add to your aquarium? Have a problem with algae, and are wanting an algae grazer? Then look no further as you have stumbled across the perfect article.

I remember having this same question many, many years ago about what was closed-loop reef tank? And if you are here, you probably have a bunch of questions like what they are too? What is their.

Crabs can be an enchanting and pleasant addition to your saltwater aquarium. Not only do they look great and add interest, but they also help to keep your reef tank clean! In my aquarium, my platoon.

If you are just getting into saltwater aquariums, and more particularly—coral reef aquariums, then you might be wondering what this term is all about, 'What is a reef ready aquarium?'. Don't worry.

#7: Longnose Hawkfish

You didn’t see that one coming, did you? The Longnose Hawkfish is truly one of my favorite fish. I know that I’ve probably said that 300 times on this website already–and I may end up saying it 2 or 3 times just on this page along–but these fish are awesome.

They look like they’re covered in peppermint graph paper. I’m in nerd heaven.

They’re amazing. And cool. Here’s the deal:

Longnose Hawkfish grow to about 5 inches in total length, which makes them appropriate for most tanks sized

30 gallons or more. They love to perch and have a lot of personality.

I don’t think you will want to start with them as the very first fish in your aquarium, but it certainly is appropriate for a beginner who has demonstrated the basic reef-keeping capabilities. There are also a few caveats when considering just about any hawkfish species–you can’t keep them with small, walking invertebrates like peppermint shrimp or crabs because they will eat them.

#6: Six Line Wrasse

#6 on this list of the coolest saltwater aquarium fish is the Six Line Wrasse. This little wrasse-cal is a hardy, inexpensive and fun little trouble maker that will zip around your tank and clean up any small bristle worms.

They also have the most amazing, and awesome eyes.

#5: Neon Goby

Okay, I won’t say it here, but I’ve written about the neon goby before. They are one of my favorite fish. Darn it. There I go again. They have an electric-bright (neon) stripe and they are cleaner fish–they’ll swim around your other fish and pick off dead scales and parasites.

This small, inexpensive, typically aquacultured fish is inexpensive, hardy, and has a ton of personality.

#4: Percula clownfish

What list of beginner fish would be complete without a clownfish? Disclaimer here, many of the clownfish species and varieties could typically be considered one of the coolest saltwater aquarium fish for beginners–but here is my rationale for why I picked the Percula Clownfish. Percs are still pretty common, but not as common as the common clownfish (amphiprion ocellaris).

They are a little more expensive than common clowns, but not as expensive as some of the designer varieties, like the Picasso Clownfish, which is a variety of the same species. They are relatively smaller (compared with the larger species like maroon clownfish) and they are less territorial than some of the larger clowns.

Overall, that makes them one of the coolest saltwater fish for beginners.

#3: Midas Blenny

Looking for a boldly colored, fearless fish to dash across your tank? Look no further than the #3 coolest saltwater aquarium fish for beginners–the Midas Blenny. Named after King Midas, the legendary fish aficionado (that part wasn’t true but the rest is), the Midas blenny is relatively inexpensive, very hardy, and beautiful to look at.

They are slender fish that seem to ‘slither’ through the water–and their blue-ringed eyes will shimmer in the light.

#2: Orchid Dottyback

You’re going to want some purple in your tank–and the coolest way to put purple in your tank is to get the #2 coolest saltwater fish for beginners–the orchid dottyback, pseudochromis fridmani. This dottyback is commonly aquacultured and will be a great addition to any tank about 30 gallons or larger. They are a brilliant purple color and they have a black line that runs up their head through their eyes.

They can be a bit territorial, at times, but so can most of the fish on this list. I also don’t have a great picture of this fish–so you can find some better pictures here:

#1: Banggai Cardinalfish

Drum roll please–oh wait, you probably already read the title above this paragraph. The #1 coolest saltwater aquarium fish for beginners is… (any guesses?) yes–the Banggai Cardinalfish.

In the wild, these fish are only found in the Banggai islands, in Indonesia. They are on the endangered species list–but they are also one of the easiest saltwater fish to breed in captivity. They are the first saltwater fish that I bred and that got me completely hooked on them. Never buy wild-caught Banggai. That’s a bad idea. But these fish are truly amazing. they are 50% stripes, 50% fins and 50% big mouths. Totally cool. The only thing better than a Banggai cardinalfish is a tank full of them.
