Have had them for ~4+ years. Started in a 120 gal. Then went between 240 gal and 4500 gal a couple of times. Finally they are in a 240 gal again. Someone in 4500 gal was bothering them too much (I have removed some fish but failed to figure out who was bothering them; they were always piled up by a drain screen), so they ate poorly.

The biggest guy at 18" is still in 4500 gal alone.

Here are 5 smaller ones, all between 12"-14", with their tank mates in 240 gal:

Been a year. An update video on the 2-footer in 4500 gal. Nothing much to add verbatim. The guy doesn't always come out from his corner to feed but when it does inhales anything and everything that it meets on its trajectory.

So cool. They look like they come straight out of a Jurassic park movie.

Fifteen month update on the smaller quintet. Nothing much to say. They might have added an inch or two, that is they are perhaps around 14"-16". They feed ok, could be better, I think, based on my prior experience but not bad. I wonder too if these are all males and the big one is a female. No grounds, no homework; just wondering why such an enormous difference. And why two of krichardson krichardson and now of Fatlungy Fatlungy (currently for sale in the Marketplace https://www.monsterfishkeepers.com/forums/threads/2-megoladorus-irwini-cats-20.716897/ ) are about 2' while they are, I assume, younger than mine, who are about 5.5 years old.
