Blue Aquarium Fish for Freshwater Tanks
Right here are a few of our preferred bluefish for freshwater fish tanks:
Blue Betta (Siamese Fighting Fish)
Despite the fact that blue is not a typical color in nature, blue Bettas are among the most well-known tropical fish in the trade. In the wild, Bettas frequently have fins that are a filthy brownish color with blue and red blending seamlessly into them.
Many captive male Bettas have flag-like fins and a striking cobalt blue color that is quite different from that of their wild progenitors because of generations of careful reproduction by Thai professionals. Bettas that are females are larger and never display the routing fins. They may also have a strong blue hue.
One reason Bettas are strong and so popular is that they are partial air rests! Because of their labyrinth body function, fish can breathe additional air when living in motionless seas where other fish would suffocate.
Consider starting a Betta Sorority if you like Bettas but don’t want to deal with the men’s homicidal manias. The best way to combine many Betta varieties in one fish tank is to join a sorority, which is a group of women who live (relatively) in peace with one another.

Blue Peacock Cichlid
Numerous Cichlid fish in Lake Malawi contain varying degrees of blue. The magnificent Peacock Cichlid, though, has one of the most intensely colored patterns of all of them. Peacocks are blue tropical fish, but they also come in albino, marble, and yellow color variations!
Blue Peacocks, which are just territorial and semi-aggressive, are ideal for African Cichlid neighborhood storage tanks, where individuals frequently dart between rocks and occasionally adopt hostile screens. In many ways, Rift Lake’s cichlid aquariums are freshwater versions of coral reef aquariums.
Heaven Peacock needs hard water (pH 7.7-8.6) with lots of liquified minerals for permanent wellness, same like the other African Cichlids from Rift Lake. Water temperatures should be comfortable (between 74 and 78 degrees Fahrenheit), but not too warm. They lose color, are unable to reproduce, and eventually perish when housed in issues that are more typical for freshwater neighborhood storage tanks.

Their small size (4 inches) makes them great dither fish for Cichlids and other semi-aggressive fish, and their amazing rainbow-like blue flanks are interesting to watch when they train each other. The tranquil Lake Kutubu Rainbowfish can be maintained with Livebearers, Tetras, and other small local fish.
They should be kept in groups of at least six and also in fish tanks no lower than 30 gallons due to the fact that they are active, educated, and also medium-sized.

Unlike some bluefish tank fish, Blue Delta Guppies are highly variable. Some men have blue tinting primarily in the back fifty percent of their body and their large, triangular delta tail fin.
Given that Guppies might wait for weeks before abruptly reproducing, keeping a hanging dog breeder box available ensures that females have a place to give birth. Additionally, you may take care of the young fry without worrying about other fish eating them!

Their lack of natural teeth prevents them from causing serious harm to themselves or their tank mates.
Gouramis, like Bettas, are Labyrinth Fish that must breathe air to move through stagnant, boiling fish pools. The Electric Blue Dwarf Gourami is a lovely option that is smaller and completely calm if the Blue Gourami is too big and expensive for your neighborhood container.

The Royal Blue Tang is less sensitive than some of its relatives. They should never be the first fish added and do need a safe, fully developed fish tank.

The Cherub Angel, the smallest Angelfish of them all, is a superb choice for tiny storage tanks looking for a blue tropical fish to boost points. Cherubs, like all angelfish, must be handled carefully in micro coral reefs.

Cherub Angelfish are wonderful additions to grow fish tanks that have been completely cycled, even if no angelfish can be said to be durable. Provide a hearty selection of omnivorous options, including vegan-based pellets or flakes, Mysid shrimp, and standard aquatic flakes.
While Cherub Angelfish are peaceful toward other fish in the aquarium, they are agitating toward one another. Additionally, regardless of the size of the storage tank, two men will undoubtedly fight to the death.

Despite their size, they are among the toughest angelfish and readily accept a variety of frozen, ready, and online foods. Additionally mild-mannered, Asfur angelfish have a tendency to be reticent and also reserved. To feel secure swimming in open water, they must be given harsh protrusions and collapse.

Although they are generally quiet, Neon Blue Gobies can be aggressive toward members of their own species as well as other Gobies, Blennies, and Dartfish. They frequently have a favorite perch, which they ferociously defend against intruders.
