Having unsuitable tank mates: This is why it is very important to keep a suitable tank mate for your fish and other animals because when they have a hostile mate, then they will always fight, chase each other around and even drag everything, including territories and foods.

Every aquatic animal has it’s own suitable water parameters such as pH, water type, temperature etc.

On a normal basis, these chemicals should be 0% in your tank because they are very harmful to every living thing, including your rainbow sharks etc.

So if your rainbow shark starts losing or changing color as the case may be, then you might have to check if they are getting stressed from anything and adjust it to reduce their stress level.

Tank size: Tank size too could lead to stress for rainbow sharks.

We all know that this fish normally gets big when they fully grow, and keeping them in a tank where they won’t feel totally comfortable and swim about could bring about stress, which could in turn lead to lose of color and aggression.

Tank size matters alot, so getting big, good and suitable tanks for your fish is the ideal in keeping a happy and less stressed fish.

A fully grown rainbow shark should need up to a 75 gallons tank to be able to swim about freely.

Also air pump, filter and heater matters alot for free flow of oxygen, water and heat in the tank for your shark to be comfortable.
