hello, I own a 9" pacu and a 8" oscar there in a 55 gallon tank and are fine for now. I also have a large koi pond. Been thinking about building another pond and stocking it with pacus and oscars and arowanas and red tailed catfish. But some pet stores say this will work fine but some say it wont. I live in north florida and the temperature can range from 90 in the summer to 20 in the winter think the cold weather could be a problem? Any help is greatly appreciated!
honestly, a 9" pacu is not fine in a 55g tank. neither is an 8" oscar in my opinion. very, very soon that pacu WILL hit a growth spurt, and in a matter of a few months, will suddenly be 16-17". you need to find him a new home now, or build your pond. take this form someone who's raised several, and still owns 2 large pacu.
a large outdoor pond, with temps that may dip that low in winter will require alot of heating. i would think you would need something like a decent propane swimming pool heater. not much else can keep up with the large ammount of water you would most likely have in a decently sized pond.
with wanting several pacu, and a red tail cat and arro's, i hope you realize your looking at a pond that will need to be measured in TENS OF THOUSANDS of gallons. pacu can and will reach 2-3 feet, same with a silver arro. a Red tail cat im pretty sure has the potential to reach the size of YOU. others may disagree, but i would say with that mix you want, you would need something like a 15x15x10. 3 foot long fish NEED room to swim and use their muscles, and to be able to swim up and down easily. granted this is an IDEAL size, and you MAY be able to get away with something smaller.
goodluck, and hope you decide to built that tropical pond. we can always use another monster fish keeper around here
