rb in a 20gallon?

  • We are currently upgrading MFK. thanks! -neo
ANYWAYS,

Arowana Man, I've changed my avi since then, and don't remember which one I had, but it's my solo RBP now.

To say that a fish will only grow to the size of the tank is a bunch of malarky if you're taking care of it properly.

A piranha cannot stop growing because he thinks to himself...well, it's getting a little cramped in here, I think I'll slow down a bit.

HOWEVER, If you never change your water, the ammonia in the water will gradually increase to a point where your fish's body will realease a growth inhibiter, simply because his environment cannot support him if he gets any bigger. Make sense?

Piranha will try to shoal with fish whom aren't even of it's species, this isn't because they tolerate each other, but because they NEED the companionship, and it makes them feel more secure... BUT, they will only be as active as the fish they are shoaling with....

My 4" RBP shoals with a pair of plecos named Lucky and Sheba, and he's not that active. (him or the plecs)

My fiance's 2" shoals with a pair of half inch YOY bluegill (they were properly quarentined) and she's ALL over her tank, and doesn't even try eating them.
 
Sushi, are those bluegill local caught? If so, where? And, as always, great info.
 
yup, my fiance lives on a private lake down here in Lenawee. I had a pair of 7 inchers earlier this year, we tossed them in the duck's pond and they disappeared....

Anyways, on the YOY, we catch them in the seine to use as bait for crappie, we had 200+ and brought home about 20 of them, we q-ed them with the goldfish, and my goldies ate all but 5 or so, the 2 we put in with Kayli as an experiment (types of fish that can house with RBPs) and 3 that stayed with my golds. We lost two of the 3 last Water Change.
 
RBP's aren't overly aggressive and don't need 75 gallons of space a piece... any fish left alone would be unhappy in a 75gallon.. all that space with nothing to share so going that big is overkill. We have 2 in a 40 gallon and its good enough to keep them happy. They chase goldfish around and have plenty of room to chase and move around. Also in our 90 gallon we have 5 2inch RBP's with a pleco and they all share the same hiding spot. To be honest from what I've seen, read and/or heard 10-15 gallons f water per piranha is plentyful and as stated keeping them alone won't help your cause.
 
I have a solo RBP and hes as happy as ever. He wouldnt tolerate any other P's in his tank, theyed be eaten. He eats anything that goes in. He even eats the amazon swords....
