| Research Information:Further research and collection data needs to be conducted in the field with laboratory examinations as well as aquaria(ecology) documentation of habits and activity. Serrasalmus Rhombeus from South America. Serrasalmus Rhombeus is quite an interesting species of piranha. From a purely amateur ichthyological viewpoint this piranha will require many months and years to properly describe what I feel is surely a complex of species. There are groups from Peru and Brazil that are extrememly varied and even within Brazil itself many fish are given the name Serrasalmus Rhombeus when being exported. This will be an interesting endeavour to study this species.

In Aquaria
Common Name:Black High-Back Piranha
Adult Size 21" TL
Minimum Aquarium Size:100 US Gallons
Temperature: 78-81F
PH: 5.6-7.1
Food: Will accept any live freshwater fish used as a normal feeder fish, thawed frozen fish fillets, shrimp and other meat products.
General Information:A wonderful fish(s) to keep in a large tank. The peruvian fish is also collected in many blackwater areas and thus seems to have a much more adaptable capability to be in a lower PH environment.
Aggression: ( 6 / 7 ) The fish is not capable of being shoaled in most instances.
Breeding:I have not been able to verify any claims to captive breeding of this species. No known instances of aquaria breeding.
