You should expect 1/2" growth every year...their growth start to slow down. Do your weekly water changes and make sure you have a large tank

75- 13" Black Rhom
i am assumeing a 75g. for a rohm is signifigant.
and the growing may even be less then that seeing he is 13''!
I wouldn't expect a lot more growth out your big guy. once in captivity large rhoms tend to stop growing. If you do get some growth I wouldn't expect to be noticable. just keep him fat and happy with lots of current.

i remember you and i had a discussion about this topic when i picked up your sanchezi. judging by how few of the larger rhoms i see in the trade, i would tend to agree w/ you. what about if they are kept in larger tanks...say 200+ gallons? i would consider my 75 a bare minimum for this fish.
he is def. a fat and somewhat happy rhom. he loves to chow down whole raw shell on shrimp w/ the tail removed.
has anyone else kept a large rhom (12+ inches) in captivity for an extended period of time? if so what did you observe as far as growth goes?
thanks for the replies,
there are a lot of people who keep rhoms that 13+" in captivity. I have never read of one that had a signifcant growth. There is something missing in our tanks that the amazon has. They come from whitewater regions that would be high in O2 so that could be a cause. Or maybe its lack of competetion for food. Or just something missing from diet. We just not be giving them the right incentives who knows, but no one has figured it out yet. A larger tank will certainly help the cause but I wouldn't put any money on it. I wouldn't expect any real sizable growth from your guy.
honestly, i never had a rhom. but the thing is: i never heard anybody say that 75g was a bare minimum for a rhom. i always heard that less than 130 was not enough for full growth. i also think that if you go see in the piranha identification page in the top of the piranha forum here, you'll see what thank size u need.
again, i never had any, but i very often saw on different websites that u need at least a 130 gals if u want a rhom... 75 may be too small for him to grow further.

this is what u can see from a Joshy posting on top of the p forum page here:
Scientific Name: Serrasalmus rhombeus
Common Names: Rhombeus Piranha, Black Piranha, Rhom
Distribution: Widespread throughout South America.
Size: 16 inches (Captive), 22 inches (wild)
Captivity: Tank size and volume depends on the size of the fish, however 100 gallons is the minimum, and 150 gallons being good for a full adult in order to reach a good size. A powerful and efficient filtration system is needed. A temperature of 24-30C, and pH of 5.5-7.5 is required.
