RBP or rhom

  • We are currently upgrading MFK. thanks! -neo
depends what you like.

rbp are shoaling p's from the pygo genus
rhoms are solitary p's from the serra genus.

rhoms grow very slow, as slow as 1-2" a year, so many people don't buy small.

red bellies grow fairly quickly.
 
Rhoms can get very large, some upwards of 18", meaning you'll need about a 100gal tank for 1. RBP get to about 12", and need about 15-20gal each. But they also do much better being kept in a group of 4 or more, since they are schooling fish.

rbp barely hit 9"-10" when full grown, 12" is out of the question. the 20 gal each rule applys after you have a 4'x12"-18" minimum footprint aquarium for the fish. and very few captive rhoms hit 18", it happens but not everyday, there are few people with rhoms in the 17" range let alone bigger. and a 100 gal for a rhom would really depend on footprint of aquarium, do to the fact that the widest 100 gals are sold commonly is 18" i'd opt for a tank with a 6'x2' footprint or 180 gallons, for fish in the 16"+ range.
 
my lfs has 12" RBP. If a fish "rarely" hits a certan size, I'd rather plan ahead and get the tank that is 20gal larger now than need it when it hits 12"...

if it was 12" than you have mistaken it for a different pygo, piraya, terns, and caribe all get larger than rbp, piraya as large as 22-24", caribe into the 15-16" range, and terns up to 14-15" (terns are classified under the same taxonamy as rpb (nattereri) but are found in a different local. you also may have mistaken size, recenetly a member here bought what he beleived was a 16" blood parrot that turned out to be 9", but if you are sure of it- take a decent pic with the fish next to a ruler and prove me wrong.
 
-XR- Don't rule out that it could've been wild caught, since almost all fish get bigger in the wild, than they do in the home aquaria.

There is nothing wrong with reds, they're hardy enough for the beginning piranha keeper, and I personally find that red color to die for. A solo redbelly isn't as great as a shoal (I love my new shoal) but sometimes it may be neccessary.

I think reds would be a good place to start if you want a group, or to "grow your own" so to speak

but if you want a BIG fish, Rhoms are great for that ^^
