My brother and I purchased this pirahna approx. 2 months ago, they were sold to us as a red belly. The size of the fish is approx. 2"+ and has still yet to show signs of red belly. We have checked water conditions and PH is 7.2, amonia and nitrate are good. We have been feeding a variety of krill, squid, and silverside fish.
Fish has losts its spots about month ago, and is a silvery gray thoughout the body with the head showing a slight pink.

Can anyone please ID this fish, and also if it is a P. Nat what addtional food items or water condiotons should we investigate to help bring out the red on its belly.

Also, the reason we are asking is because this is our biggest prirahna out of the six we bought. The slighly smaller pirahnas out of the bunch are already showing signs of a colur change around the gills. So we are wondering if these are two different species or do some pirahnas hit puberty at different times.

Well we are taking the above replies as a compliment! We have been feeding our pirahna once a day, will keep the group posted on this guys progress. He attacks the krill and sqid and usually once the other priahna see this they do the same. So far he is not a picky eater (egually likes krill, squid, and silversides), We also have comuntity fish in the tank (tiger barbs, tetras, guppies, swordtails, plceco) and so far we have not lost one.

Two questions:
1)As they get older will they become pickier and also eat the other live fish in tank?

2)What food helps colour the best?

they will evently eat the other fish in the tank when they get bigger and they probably wont get any pickier with there food

and for best color use shrimp un cooked with the shell

OK if that is a Pnatt at juvenile stage then how did he lose all his spots already? and why is his anal fin have only a little red in it?

and its ALL silver mostly and has almost clear fins?

IMO i dont think its a P.natt or maybe an albino natt

it just dont look like any of the reds ive raised...from dime sized

and if it is bigger than the rest its becuz maybe hes getting more food than the others..but u also said that the other reds even they are smaller have a little red on theyre bellies...

Well wait a MONTH and take ANOTHER pic of this fish i would really like to see how he develops and maybe we can help more on identifying this fat ass P u got

It dont look like this Juvenvile Natt

u see even at this age at 9-11 weeks old he still has his spots...even my red who ive had over 2 yrs still has some spots u can see
