Dottybacks

For large tank

Dottybacks are aggressive and territorial. You must have a large fish tank to keep them but they can also live in a smaller tank. Although they are fairly low-maintenance fish, they require a mature saltwater aquarium with ample hiding places. Their immune system helps them withstand a variety of water conditions, including disease outbreaks. They grow to an average size and belong to the Pseudochromidae family, which includes over 100 species.

A dottyback is a colorful and attractive saltwater species that looks amazing in any marine tank. Its half-purple and half-yellow body give it a striking contrast to any marine tank. While they may appear innocent, this critter can be very aggressive and pick on smaller fish and invertebrates. Because of this, it is not a good idea to keep them in a small aquarium with sensitive fish species.

Dottyback species profiles

Dottybacks are small, aggressive, and hardy saltwater aquarium fish. Their distinctive swimming patterns make them ideal starter fish for beginners. The smallest of the species, dottybacks are capable of thriving in a 30-gallon tank, but be prepared for territoriality and aggressive behavior. Besides their aggressive and territorial behavior, these fish also need a healthy diet. They are best fed meaty foods and preferably large rock formations for hiding.

Although dottybacks can be aggressive, they do well in a community tank or reef environment. They are good tankmates if you have live rock in your tank and provide them with a cave or crevice to hide in. Dottybacks do well in tanks with other peaceful fish but keep them separate from conspecifics.

Green Chromis

For 30 to 60-gallon fish tank

A school of green chromis is a great addition to your aquarium and will thrive in a well-lit space. These hardy fish can be kept in 30 to 60 gallon tanks. While they can live happily in large groups, they should be kept in loose formation so that can swim around freely. They are active during the night, so they should be kept in a tank with good blue lighting.

Despite their aggressive nature, the Green Chromis can be a friendly addition to any community aquarium. They tend to hang out in the upper water column and enjoy swimming around corals and rock formations. As a result, they are great for reef aquariums. They are reef-safe and are compatible with other fish. However, it is important to keep them away from larger fish.

Chromis profiles

Green Chromis are excellent eaters. They can eat almost any type of food, and will happily eat frozen Krill or Mysis shrimp. In addition to their preferred diet, you can also give them liquid vitamins or supplement them with finely cut vegetables. The amount of food you feed chromis will depend on the size of your aquarium. It is best to feed them 3 times daily.

The Blue Green Chromis prefers to live in small groups. Majority of these fish prefer a peaceful environment, and will be compatible with many other species of peaceful saltwater animals. Be careful not to keep them with large fish or eels because they will overpower them. If you don’t want to deal with that, keep them in groups of at least six. When you have enough space, a group of green chromis can live happily and peacefully in groups.

Six line wrasse

If you’re looking for the coolest saltwater aquarium fish for your tank, the six-line wrasse is the one to go for. Known for their bright red and black stripes, these fish are also quite aggressive.

Six-line wrasse can live up to five years in the right conditions.
