In general, the fire mouth fish should be mixed with fish larger than it. Because the fire mouth fish itself is very aggressive and likes to attack other fish actively, it can be mixed with larger fish, which can suppress it in size, so that it will not be too excessive.
At that same time, it can also be mix with some fish that are hotter than it, so as to suppress its fight situation. Therefore, craterfish are best mixed with larger or more grumpy fish. Specifically, it can be raised with parrot fish, map fish, arowana and other fish of similar size.
Fire mouth fish and parrot fish can be mixed culture together. First of all, the living environment of parrot fish and fire mouth fish is similar, and they can live at 25 degrees Celsius. Moreover, the water quality requirements of the two are not strict, and the choice of food is similar, both can be fed with red worms, earthworms and so on. Although the fire mouth fish likes to fight, the size and aggression of parrot fish are stronger than that of fire mouth fish, so the aggression of fire mouth fish may be suppressed in the process of breeding. However, when mixed breeding, we must use vats, otherwise there will still be fighting incidents.
