The Saltwater Aquarium Groupers are a large and aggressive saltwater fish that will thrive in very large aquariums. Most of these creatures grow up to 12 inches long, so you’ll need plenty of swimming room with hiding places for it too! They can be kept as reef tank inhabitants but they’re known feeders on smaller animals like shrimp or other fish given the chance – this is why some people keep them only just out into their own personal ponds at home instead.
10 Best Saltwater Aquarium Groupers
This is a great saltwater fish for anyone looking to add some biomass and color to their aquarium. They grow in excess of 15 inches so they need large tanks to thrive. Their skin has an olive pattern that makes them look like small underwater forests when seen from above, giving them the name Miniatus grouper. This camouflage serves as good protection against predators but if kept in an aquarium such features are merely ornamental.
They’re not picky eaters and will devour whatever food you give them with gusto; make sure you don’t go cheap on your purchase though or they’ll turn up their noses at it and refuse to eat! If you want one, make sure to take this into account and spend a fair amount on quality food.
The Clown grouper is the largest of all the groupers, growing up to 6 feet in length! It’s also one of the most colorful fish out there too; with bright orange stripes it looks just like a clownfish! If you’re looking for something truly spectacular to keep in your saltwater aquarium then this might be what you need. They’ll only grow about 15 inches long but if kept in large tanks they can grow quite quickly so make sure you factor that into your expenses when keeping them. Despite its size it still isn’t considered safe for reef tanks unless they have extremely high filtration systems with very strong pumps because like many larger creatures they produce significant amounts of waste that can sometimes be harmful to the other inhabitants.
Another large saltwater fish that can grow up to 12 inches long! This one has dark stripes with an orange tint, making it stand out even more in your aquarium. Care needs to be taken because they’re what’s known as a fin-nipping grouper; they’ll eat smaller fishes and shrimp if you’re not careful! They do well in very large tanks though so those who choose to keep them will enjoy their vivid color and beautiful symmetry as they swim about.
Red V-Tail Grouper:
One of the smallest groupers at only 5-8 inches long, this one is also extremely aggressive! It’s almost impossible to house one with other species because it will prey on anything that moves.
It’s also known as the square-tailed grouper, so named because of its square tail fin. They have faint stripes running across their bodies which are extremely colorful when viewed from above, adding to their beauty in an aquarium setting. The only downside if you keep this fish is that you’ll need a 2 inch or thicker glass lid for your tank to prevent escapes!
Cherry Louti Grouper:
This is another very beautiful saltwater fish but it doesn’t grow quite as large as some of the others at around 11 inches long maximum. They come in shades of white and light reds with short black stripes running along their bodies – the name Louti is Greek for “stripes.” They’re a very gregarious fish and can be kept as a group as long as you have the tank space.
One of the most spectacularly colored saltwater fish, this one grows to just over 10 inches long. Its colors range from black and dark red to come shades of purple and blue so it will stand out nicely in your aquarium. It’s not a picky eater but needs large tanks with plenty of hiding places because if housed with other creatures it may try to prey on them at every opportunity! The smallest tank you should keep this grouper in should be well over 100 gallons to give it ample room to grow and swim about as it pleases.
This grouper gets its name from the distinctive saddle shape on its back, running from its head to tail fins where a lot of other fish have their fin-base. It’s very similar in appearance to a juvenile red banded grouper and can grow up to 10 inches long over time so it’s certainly not suited for small tanks. They do well when kept with their own kind but need lots of space because they produce large amounts of waste – again, you’ll need strong filtration systems if this is your chosen species.
Blue Spotted Grouper:
A beautiful saltwater fish that grows just under 12 inches, this one has clearly visible blue spots covering its entire body that are still visible even when it’s fully grown. Like other grouper fish they’re very territorial but can be kept with their own kind as long as you have a larger tank, over 100 gallons preferably. They’re not picky eaters but their feeding habits can cause problems with aquarium inhabitants so be sure you know what you’re getting into if this is your chosen species of saltwater fish!
Blue Line Grouper:
This one has blue and yellow stripes on its body and grows up to 10 inches which makes it another good option for an appropriately sized saltwater aquarium. It won’t do well in small tanks unless you want to keep it alone – if housed with other creatures the blue line grouper is fast, aggressive and has even been known to go after larger fish like sharks! It’s not picky about its diet but can cause problems with other inhabitants if you’re keeping it with them because of what it eats.
This one is an oddity among groupers; unlike the others which are typically found in saltwater this one can live in both fresh or brackish water. It’s grown for its vibrant colors rather than size so won’t get too large at around 8 inches maximum length. This particular species only needs small tanks so they’re ideal for beginner aquarium owners who don’t have a lot of space, although they will need special care to their living requirements being so specific. This is the only fish on the list that can be kept with other creatures without any problems, although it’s important not to house them with anything too aggressive just in case.
