How big tank you keep pterygoplichthys pardalis?

[Kaetsy]

So, here is my question about year ago, i rescue little brown, dark spotted pleco in too small(and cold) gold fish tank. Then i didnt know what pleco it was. My tank is about 500liter (115 gallon) and the ground is 200cm x 50cm (78inch x 20inch) . When that pleco is adult that is not enough ? (If they Grow 20inch long in aquarium?)
How long it takes these plecos are full-size? I know it depends Many things, so maybe i need to ask how long it takes your pleco is full-size? he is now about 9inch .
I ask that because i can/want take bigger aquarium just i can keep that pleco, but my apartment floors is risk.
The current aquarium is good for me if this pleco fit to live there his life
I have also L200, L075 and L204 in same tank and couple cichlid species

If you realize Pt pardalis will grow to 35 cm, I would not consider your tank is f sufficient size.

A fish should be able to turn around in a tank - that is, a 35 cm fish will need 70 cm from front to back.

Were your tank 200 * 70 * 50 cm, that is 700 liters, I would consider it sufficient. 500 is a bit of a tight fit, but the real problem is the distance from front to back

Yes, i know how big it grows, and i know maybe more than 35cm... When i take him i didnt know what species he is but now when i know im worried about that.
Just why i think how fast it grows in that size...? Because i'm ready to take bigger tank - but not in this house (old house and the floors isn't good) . I live there maybe a year more (is other reasons also why i move not just tank )
I mean that when i say tank is enough big for me IF that pleco fit to live there, but if it doesn't i can take littlebit bigger. It is real problem that tank is only 50cm from front to back
And p.pardalis is growing so fast im worried is it too big too fast and of course i find him new home then ...but it will broke my heart

Don't know about P pardalis, but I got P gibbiceps @ 6 cm in October 2003. They were 17 cm after a year, and 30 after another

Now I think they don't grow anymore, and measure some 50 cm - including 10 cm of fin on the tail

Assuming P pardalis has a similar growth pattern, they would take 2 years to get from 20 cm to 40 (that is, including the tail fin)
