ARAPAIMA MAX 60cm in CAPTIVITY??
- Thread starter Alligator head
- Start date
What if they r kept in a small tank for long! Like there are people who keep goldfish in a pot! I personally know a guy who had a goldfish for nearly 2 years in the same tank at the same size! Would it also be same with these beasts
Then they certainly won't live to max size, and won't live long either
Oh I even heard the lfs guy telling that these arapaimas in aquarium don't live longer as they are given small place he was like they can live in the 500gallon aquarium for 7-8yrs max!
They need thousands of gallons of water to thrive and grow to their full potential.
Just dont even think about buying such a fish if you cant offer more than at least 4000 gallons. And even that is pretty damn small for such fish.
This is a common theme for large growing fish. Whether intentional or not people frequently underestimate growth and max size of fish. Some of it is from people trying to make a sale, some from stunting and some from those who just don't know any better. Given proper conditions many of the monsters we keep grow very large.
i would imagine most don't exceed this length in captivity because they die first
