yeah im doin my research. feel its a must - to hell with expensive "failed experiments". if i was rich i'd have a 1200 gallon amazon biotope with about 4 rhom's in it. i found a great website that tells tons of useful info. the guy who did the site has been researching pirahna since the 60's-70's from what ive read. VERY NOLIGABLE. he said the only 2 cases of black rhom's breeding in captivity was in a 1200 gallon aquarium in germany in like 1977. the breed and the babies were takin out to grow to about 6" and some where put back in there. then another breeding occured and they left the babies in there and the parents killed them all. also from what i gather they play well with each other till about 6" or so, then all hell breaks lose. they do grow slow after they hit the 5" mark, but the guy thinks its because of stress, tank size, diet all mixed together. so, just assuming you could replicate there home enviroment in a big tank to reduse stress and tank size issues, and replicate there diet. you could probably get one to grow fairly quicker.
why i want pirahna? well, i want something with teeth. that doesn't get 4' long. a true "river monster" and top predator. i know i could pick up some rbp's for cheap, they'd shoal, breed, etc... but whats the point? nothing wrong wth rb's - there just a little to common. like i know 2 people who have / had pirahna's. both people had 4-5 rb's. the only other options i know of are, piyara (spelling). there expensive and i hear they dont live to long in captivity. plus the size they can get. not done alot of research on them tho. just a litte. the tigerfish. there bad asses, but @ same time, thats a fish with huge growth potential, and i don't want to be the ******* keeping a huge fish in a small tank and stunt its growth and shorten its life span. plus they are pricey. way more than i wanna spend on a fish.
jp - nice pic's. thanks for that info.
if anyone has idea's for species/breeds of fish fitting what im looking for im open to suggestions. always am. i plan on taking my time with this to make sure its done right. still have alot of research to do on making a black water amazon biotope. wood to use, how to make water that color, the plants etc....
