Some of the most common and so-called hardy butterfly fish that I would recommend to advanced marine aquarist generally comprises of longnose, copperband, teardrop, pyramid, raccoon and threadfin fish. Usually the best aquarium setup to house your pets should have a system well-equipped with protein skimmer and coral sands, which acts to control the pH within 8.2 to 8.5 while the temperature should stick to the 78 to 85 degree Fahrenheit range. Apart from that, a powerful filter system should also be present because without these, you will have a hard time maintaining perfect water quality.
Mixing your butterfly fish into a saltwater community tank should be done with extreme care. A good rule of thumb would be to avoid basses, lionfish and triggers while tang and angelfish might be fine provided that your reef system is large enough for each fish to thrive well without disturbing one another. When it comes to breeding your butterfly fish, little information is known about how the whole process works out and it’s very rare to hear success stories of marine pet hobbyist who has successful get the fish to spawn in captivity.
