Small aquariums do not stunt fish growth; excess metabolic wastes and overcrowding do. Both are difficult to prevent in undersized aquaria, though, and thus perpetuate the perception that it is the small tank which is directly responsible.
120cm max?....... Bwhahahahahahahahah!
Try six feet long and up to two hundred pounds.
best thing to do with a Red Tail cat is release into the wild...
In its natural SA habitat!

would this mean that, given an adequate filtration system and a small number of fish, a red tailed catfish could be kept in lets say a 30G tank? This doesn't sound right to me but thats how I perceive your post.
Lets take it one better DDayton21,
Lets say a 100gal tank submerged in a South American river, water flowing thru it, no tankmates and appropriate diet.
End result a stunted and deformed fish as it tries to grow to its genetically predetermined adult size within the confines of its enclosure.
my thoughts exactly chile. I wish it were true that fish grew to the size of the tank with no problems... but thats like putting an infant in a 3' x 3' cube and expecting it to live a healthy life.
