I would guestimate that the majority of Managuense that are in hobbyist tanks are no more than a foot long. 14" would be on the outside. Most fish have to be alive for a decade before reaching that length. I have yet to see one of the "monster" managuense that people talk about....either in a tank or in the wild.
couldnt agree more with you mojo. seems like very few reach over 14" or so and hardley any get to the mythical 17"+ that people mention. could be similar to why theres maybe only one dovii in captivity that has reached the 24"+ and most max out around 20" and its a combination of water chemistry, genetics, tank size etc..
