I think common sense will tell most people that a fish in a confined aquarium will not grow to the same size as a fish in the wild that is living in it's natural habitat.
Since you disagree with me, the department of natural resources , the florida fish co-op and most people who show or breed cichlids...
Care to explain the reasoning behind that? It may be interesting or new information.
Use your fish as an example
I have a similar size Arican Cichlid tank with predominantly Blue Zebras that can get 5"-6" at maturity
Fishbase lists all (species sold as) blue zebras as reaching 4.4" or less (based on wild averages)
So it would seem your own fish prove fish grow larger in captivity? But you don't belive they do ?
regardless of evidence shown to be contrary
Quality matters
and when a webpage, cites a place as it's referance and contradicts size by half , doesn't that seem odd ?

I'm not an "expert" with expertise advice,theres too much to learn to be an "expert" but I'm involved in this hobby enough

, that I know enough

,definately enough to belive proof and science over wrong info given in a store or found on a webpage

Take my input or leave it,it's up to you,thats what forums are for

But you might want to revist sites your saying contradict and have a look around

go back to that badmans site and read the oscar profile

The eggs are colored to match their environment and adhesive and are laid in the open, on a rock or a large leaf.
Find one person here who's had oscar eggs colored to match the environment ,in Thousands of spawns,no matter what the environment looked like all my eggs looked the same

check the green terror profile and you'll see a profile on a mislabeled fish - the same one fish stores mislabel and people belive - same thing for severum

Go to the other - wetpets site
Check out fenestratum -
perfect for the size issue males may reach to around 30 centimetres

I've imported "38-40 cm"
<-- as offered that came in slightly larger.
in the aquarium....
males reach around 25 centimetres
There is one (maybe two) members on this forum with larger
males and females If Benz sees this post I know he currently has a 31cm or larger male,in an aquarium

and what is
Amphilophus sp (Red Devil)

The species is
labiatus and has been such since 1864 when Gunther revised
froebelii
again quality matters
Info from me (or here in general) might not be 100% perfect but it's not almost 150 years outdated either

This is how myths in this hobby stay alive

Show people facts and the still clinge to what they've read or heard no matter if it's right or wrong,until those who know give up
