red pacu
 

i have 2 small (3") red pacus. i have them in a tank with 6 zebra danios.... they seem to get along great now but when i first put the zebras in the pacu chased one all around but couldnt catch him.... now they seem to just live together..... will they end up eating the danios?

Simple answer, yes.

+1

yes, i suggest taking the danios out unless they are food.

...yes...pacus also get HUGE :shock: ...they'll need a massive tank soon!

300 gallons per pacu is something i would follow, ive heard of 33" pacus (nearly 3 feet long, plus they are tall too which means that they have even more inches)

No ive looked online at everything and 300 gallons seems good. They are very very large fish, both long and tall, the 300 gallons is more for space rather than filtration.

30 inches long, about 10-15 inches tall, add those together, 45 inches adult size, add filtration needs and food, 300 gallons is my summary, Plus how deep they are. Ive seen a pacu as big as a man's torso.... They get pretty darn big.

And they have been known to ram the sides of tanks and break them. When you get into the 300 gallon range, you're talking extra thick tempered glass which may, possibly, and I ain't going to be the one testing this and winding up with 300 gallons of water on my livingroom floor, prevent this.

Frankly, I think you're both right - 75 gallons per pacu sounds reasonable, but 300 gallons sounds like a good minimum size tank.

i looked it up and this guy has one and had it for years in a 5 gallon tank and its doing fine.
