Tropical - Fish - Pictures .com

This is a tropical fish site for all tropical fish enthusiasts from beginner to expert. It has some nice tropical fish pictures and will hopefully have something of interest for all freshwater and marine fish keepers. These tropical fish pages provide some information about some of my favourite fish, along with tropical fish pictures of them. I have kept fish for many years now, ranging from community to marine. Over this period I have been drawn towards catfish, and the cichlids, which I must confess, through there antics have become my favourites. I now keep African and American cichlids, along with some catfish and plecs.

Red-Bellied Piranha

Picture of Red-Bellied Piranha
Common nameRed-Bellied Piranha, Red Piranha, Natterer's Piranha
Scientific namePygocentrus nattereri
SynonymsSerrasalmus nattereri (not valid)
Size12" (30cm)
OriginLarge areas of the Amazon and its major tributaries.
Tank setupA large tank with bogwood, and a few robust or plastic plants for decor. A shoal of adults will require a tank of 100 gallons plus. Heavy-duty filtration is essential.
CompatibilityA highly predatory carnivore, keep in a shoal in a species tank.
Temperature24-27oC (75-81oF)
Water chemistryFairly soft, acidic water (pH 5.8-6.8) prefered, but not essential.
FeedingCarnivore: Live or dead meaty foods. There is no particular need to feed live fish, as they can easily be weaned onto thawed mussel, prawn, etc - some even take pellets which can help to provide a varied diet. The use of "feeder fish" carries a strong risk of introducing disease.
SexingNo clear sexual differences. Breeding females may appear more robust in shape.
BreedingEggs are laid among plants or in a pit in the substrate and defended by the parents. Hatching takes around 2-3 days.
CommentsThis fish is infamous as a highly dangerous carnivore. Although its reputation is somewhat exaggerated, it is wise to take precautions when carrying out tank maintenance. The fish may actually appear rather timid if kept in a brightly lit aquarium with little cover.
This species may be confused with P. cariba, which occurs in the Orinoco river, rather than the Amazon.
