Has anyone ever maintained this species to the size depicted in the accompanying photo. Makes me want to keep this species again.

I've kept them a few times the biggest ones I had were 6 inch males, before I passed them on, the biggest one I saw was at an aca which was around 7"...to answer your question

Mine were that large too, when I traded them off. Perhaps only a small percentage of males reach such large sizes?

I've seen hem in a shop, only slightly smaller. I was fired the dat before, in 1997, and therefore did not buy them - something I still regret

newworldsss, I think you are confusing this with the common Red Hump, G. steindachneri. I've had crassilabris, but I have not seen true pellegrini here in the US.

The hump on that head is amazing. I have to wonder how the fish could swim with that thing sticking out like that! :)

Darrell no confusion here, I've had all 3 of the red hump complex, as for not seeing the true pellegrini they were around, there are a few venders who had them recently, adults of all 3 are easily distinguished from each other.....maybe pellegrini weren't around maybe 10 years ago but things change...looking at your location I sold a pair to a fellow you might know (local?) under the name Steve Morrison at a aca a few years back....

True pellegrini started coming in with the other shipments of new fish from Colombia a few years ago that included the 'Cichlasoma' cf. gephyrum. They are fantastic looking fish, but I haven't yet seen one with that kind of hump in captivity.

The hump depends on seksual competition. Once I raised a nest of G steindachneri. The alfa one did not have any hump - it did not have to compete for its position. Fish delta, epsilon had far greater ones - they competed with almost anyone, and had hums just as insanely big as the above fish has. Mind you they measures some 5 cm /2 inches
fish omega did not have any hump either - it had given up all hope of ever geting higher in the pikorder

This fish, with this hump does remind me of a delta fish, that is, there are even more dominant ones in the water. Somewhere

But that implies having some 6 or more adult males, together with at least the same number of females, in 1 tank. That tank better be huge

Guess I'll have to start looking around. That's what I get for being out of circulation for a few years. :oops:

It would be nice to see more wild caught G. pellegrini exported again soon.

About two years ago there was an import of pellegrini, adult wildcaughts in one of Dutch wholesalers, but I had no opportunity to get them from there. And they were pretty cheap for an "XL" size (whatever this means). These (along with crassilabris) are very high on my wishlist.

That's really impressive, thanks for posting. It should be noted that the photo (which I found on several websites) is originally from the NRM collection database. The fish was collected and photographed by Sven Kullander in 1989. With it, two other large specimens where taken (and photographed), another similar male and an obvious female, also of extraordinary size:

Such a fish in a sufficiently large tank would definitely be an eye-catcher.
