Serrasalmus rhombeus, diamond highback a very strong thick set fish from Peru. A shiny scaled fish with red eyes these fish look great in the aquarium. In the wild these fish can grow to 16" long in the aquarium it takes much longer to obtain these sizes. The highback like many of the rhoms does not shoal in big groups as much as the Pygocentrus genus but mainly in small hunting packs. In the aquarium they feed well on ox heart, pigs heart, white bait, lob worms and all meaty things growing a good 1-1.5" a year with plenty of water changes to keep the nitrates down and good filtration, decor should include gravel and bogwood. Growth size: up to 15".
Serrasalmus negra, black piranha from Peru can grow to at least 18" plus. They are a chunky fish with a powerful jaw which are capable of a lot of damage. When very young they are a pretty fish, light in colour and quite bold turning quite dark as they progress in life. They are not a particular aggressive piranha in the wild but once it has found its territory in the home aquarium can become quite aggressive. Good filters and plenty of water changes are necessary for good growth. Aquarium rhoms will grow 1" to 1.5" a year with plenty of water changes. In the wild piranhas will grow a lot quicker because they are constantly swimming in fresh water, unlike in the home aquarium.
Rombeus Piranha Care
MINIMUM TANK SIZE
All types of Black Piranhas are solitary fish. Unsuitable to share a tank with any other fish.
You will need a tank of at least 120x50x50 cm. (48x20x20").
Plants, rocks or drift wood to provide hiding places, the tank lights should be dimmed. Heavy filtration is required to deal with the large amounts of waste this fish produces. A powerhead can be added to provide currents. Care is required in handling, extremely dangerous to hands.
24-29 degrees Celsius (76-84 degrees Fahrenheit).
pH should be between 6.0 - 8.0, ideally slightly acidic to neutral water: pH 6.5 - 7.2 . Soft water is preferred.
Extremely dangerous to others. Should generally be kept as solitary fish.
Fish (whole, fillet or feeders*), shrimp, cockles, mussels, squid, insects, earth worms, pellets. Food items such as poultry, mammal meat and organ meat should be fed sparsely once or twice a month at the most. Meat needs to be unseasoned and trimmed of any fat.
*Live fish need to be quarantined first, so they are safe to feed (containing no diseases or parasites). Goldfish, minnows and other members of the Cyprinid family (Carp-like fish) should be avoided, as these fish contain growth-inhibiting hormones (Thaiminase/Vitamine B1 inhibitors) that could negatively affect the fish's health and development.
