have read a lot about it, and think it could be rigth...

but if you think about it, in the wild they dont grow up in small ponds or small places... they born and live in the bigest enclosures, rivers, lakes... and dont get stresed because of that

havent seen palps in the wild, but I´ve grown mine in 5 ft round plastic pools with out problem of stress

just my 2 cents

cheers
