What do you have in the tanks with them? And what size tanks are they in?bernie comeau said:Well a male convict seldom developes a hump as large as a male Steatocranus casuarius would. And dependant on what you have already stocked in your 55 g, a Steatocranus casuarius may very well be a better choice for your tank (?).
But it is nothing unusual for a male convict to develope a nauchal hump.....though some never do. And they certainly don't have to be neither large nor old to develope a large hump, though I supose a very large hump is more typical of a larger and older specimen . I've had nauchal humps on smaller 1yr. old males that were much larger then the one on my current male con. Seen many on much smaller male cons that were a MUCH larger hump then on any I have ever owned.
My striped male at 3 yrs. of age (3 yrs. from being layed as an egg, not from being purchased---a fish from an LFS is probably already 3 months to 6 months old or more):
My 'pink' male con at a little over 2 yrs. of age (from being layed as an egg):
True both are large 6'' males, but I certainly don't regard either as 'old'. And as I mentioned already, it is nothing too unusual for much smaller and/or much younger males to develope nauchal humps that are much larger then either of my males. Though some never do.
Gave the 'pink' male away just over 1 yr. ago. Striped male became intolerant of him---started to chase the 'pink' male around too much. They have same mother, different father; 'pink' male about 1 month older and they have been in the same tank pretty much all the time since they were young fry. 'pink' male was a 'freak' at a very young age----stood out as significantly bigger then his siblings at the fry stage and was absolutely humungus for a male con at 6-7 months of age-----but at 1 yr. of age, both males were of very similar size. They have been in 33, 100, 75, 125, but mostly in a 180 gal.Chubbs the Jellybean said:What do you have in the tanks with them? And what size tanks are they in?
