DO WILD CICHLIDS DISPLAY MORE VIBRANT COLORS THAN SECOND GENERATION FISH

[caribemob]

I'll take photos of a 24-25" dovii male tomorrow night that is 4th generation in the SAME tank. Show me one that size in the wild. Fish in captivity get larger and live longer than their wild counterparts. Think about it. More food and no predation.

Did you say fish get bigger in captivity then in the wild? and yeah you might have a photo of a 24'' 4th gen dovii, it doesnt mean that a wild one can't get that big bro. and like i will say again, my fish is 6'' with a huge hump and jaws that i've never seen come that quick on a captive bred dovii Man

Fish can & will adapt to changes over time. Feeding habits are altered usually in an aquarium as oppose to the fishes feeding in the wild. Size can also adapt. Example maybe a CA in a clear water area needs to show as much as itself off & be as big as possible to show to the opposit sex & to defend its territory which can be large in the wild. Then in an aquarium unless a public aquarium it does not need to have all these traits because its glass box limits what it needs to do or act?

To answer a ? in the other post why a store sells & or loses money with the CA cichlids. I'm a retailer & do & have carried a number of fishes in the group & have had my loses trying to house in the same aquarium(s). I had tried to do a 155 bow display show what some of these beast turn into so then in turn sell fry more easly like my Aul peacocks. I had a f1 pair of Vieja synospilum, boucorti, & argentae (spelling?)& large sailfin pleco. All were around 6 inches & did well then they decided to kill their mates farely quick. Then started to turn on each other. Now they are all in their own tanks.
A problem with retailing these busters is they tie up a tank for one fish & not always sell as fast as haviing a 100 angelfish in the same tank that get sold quick. Cost to house & feed them can deter a retailer to sell them.
I'm not a normal store though & have a few hundred aquariums/hatchery & some big tanks plus I like the fish myself.

Mel said that fish may be as big as 28 inches, that is a monster dovi. That is what I am striving for, but you have to remember he has his fish in a 600 gallon tank and the fish is quite old, 6 to 8 years old.

Mob you can see that fish on youtube, look up guapotemel, they are his videos.

I said no, i have wild caught and f1 geo red heads in the same tank. I would say the only thing i notice is that the f1s are growing 3x faster than the wild caught.

First of all, there is really no way of knowing the maximal size of a certain species in the wild, because it's virtually impossible to catch all individuals and then compare. So what we call "max size" is really an estimate based on the largest individual ever collected.

Per Felipe's account, some Australoheros species get huge in captivity, much larger than any wild fish ever collected (and he has caught plenty of fish!). Monstrous, in fact, by Australoheros standard. So yeah, it can happen.

But to be fair, many other species don't grow to the "max size" in aquarium as they do in the wild. The question is why - is it genetic or environmental. A simple experiment is to take two individual juvies, one wild caught and one tank bred, and raise them in the same tank and see what happens. I have not done this myself and cannot speak to it, but I'm sure others have tried.

All wild animals live longer and get bigger in captivity, if kept in the right conditions. Just think, an old fish that may be crippled by age becomes a victim of predation in the wild. In captivity he is fed and may even be separated from others that may attack him, hence he continues to grow. Fish grow until they die, longer life, bigger fish.

The ONLY wild fish that I have seen that changes in captivity, and it happens almost immediately not over generations is the Amph. Labiatus. The wild caughts have the huge lips, but after a short amount of time in captivity those fish lose their large lips. There is one guy that I see on here sometime, Reagan, he seems to be able to keep the original look of the labiatus (red devils for those of you who do not participate in the technical names) in his fish. I believe it has something to do with the way the wild fish forage using their lips to gather or dig around for food.

At one point you had some guys on here who claimed they could tell a WC peacock bass from a farm raised one, but they could never give you a definitive what they were looking for. They claimed that they had "the eye" for it, but could not explain it. That was a fun conversation.........

I would certainly agree, but tank size, water conditions etc are important factors too. Not everybody give their fish that much room like you do

Notice I said "if kept in the right conditions" always leave yourself a way to retract your statement by framing them with conditions. That way you are rarely wrong, you can always fall back on the parameters that you referred too, we do that in the legal world........

LOL you and words

I kept tank raised and wild caught Geophagus orangeheads "tapajos" at similar sizes. The tank raised ones were bred by Ed and I held them briefly for Sue (top pic). The wild ones were imported from Brazil (bottom two pics when they were smaller and bigger than Ed's group).
