Meta-description. All rainbowfish are magnificent. However, not all of them are rainbowfish of good quality. View these steps to know about it

An elegant tank means the elegant fish inside. One of the elegant fish that you can choose is rainbowfish. Its shimmering colors in the silver background can shine in your tank, and blend so well with any kinds of the aquatic garden that you've chosen before. It is also kinds of active fish who loves to swim, so once you decide to keep the rainbowfish, you will be indulged with the attraction of fish that seem like they are dancing every day. 


However, this ultimate goodness can also be yours if you pick the right rainbowfish for your tank. Confused? Here are some tips on how to choose rainbowfish of good quality:


1. The color is bright 

As a fish known for its magnificent color, the high quality of rainbowfish, of course, has a bright color. The brighter, the higher the quality then. Not only bright, make sure that its body is not covered with phlegm. Once you find a rainbowfish that is dull in color and covered with phlegm, then it may be infected by Costia necatrix protozoa and it is not the rainbowfish of good quality


2. No white drops in the gills 

When you find the white drops in the rainbowfish's gills, it means that the rainbowfish is infected by a parasite called Ichthyopthirius multi fillis. This parasite can lead the rainbowfish into a serious problem because they can eat the rainbowfish's blood cell and make them die. 


So, always check the gills part where you buy the rainbowfish because even though it is hidden, it is one of the most important parts of the fish. 


3. The head and the back part is clean 

Make sure that the head part and the back part of the rainbowfish is clean. There is no yellowish layer on that. If you find the yellowish layer in the head and in the back, you must be suspicious. Whether it is too dirty or it is infected by Tricodina sp. 


4. It schools actively 

Rainbowfish is actually an active fish. Therefore, if it looks too limp, too skinny, and cannot move and swim actively, then there must be something wrong with it. It may be stressed, or the worst, infected by the bacteria like Pseudomonas. 


5. No fur in the body of rainbowfish. 

Rainbowfish body must be clean, must be slick, and the silvery background can reflect the light perfectly. If there are some fur that bother the silvery background to rise and shine, it means that the fish is infected with various bacteria. The bacteria can infect when the fish is hurt. And when it gets infected, it can bring bad impact to other fish in your tank. 


Clean, agile, shining. Those are the things that a rainbowfish must have. You can say that we are not allowed to judge the book by its cover, but, it doesn't work on the rainbowfish of good quality, right?
