Hi,
this is one incredible handsome guy! Extreme nice colouring!!!
But i have some questions about the lates niloticus in general:
1. I always thought, that lates niloticus is able to reach tremendous size and weight? Fishbases states records about over 6 feet and over 400 pounds?? Who one is able to keep such a giant??
2. I also thought that the nice colouring is going away with the years.
3. So as a conclusion of my twi first questions: Is this an all new kind of lates niloticus? One which is able to keep its colouring for it's hole livespan?? And which is not outgrowing nearly every possible tank?
Are there even more versions? how many are there 2? 3? I've never reed anything about this, where can i find more information of these special niloticus?
Greetings
Thank you, I like his coloring too.
I'll try and answer as best I can...keep in mind, I'm a hobbiest not a scientist so these are my opinions and should be taken with a grain of salt.
1. Yes, many sources list the max size of
Lates niloticus as 6ft and some state 400lbs+...they are listing MAX size...not average size.
Concerning max size listings on fishbase or other sources...IME many of the max sizes listed for purely ornamental fish are less then what you can probably get from them in captivity.
However, I think the max sizes listed for alot of the types of fish that support either a commercial fishery or a sport fishery are just what they say they are...MAX size...not average size.
Will every
Lates niloticus in the wild reach 6ft and 400lbs if allowed to live out it's natural life span? Absolutely not in my opinion... alot of factors come into play to create a record fish...genetics, diet, temp, water quality etc evidenced by the variations you will see in fully adult fish of all species.
If you contact the sportfishing guides in Africa that specialize in Nile perch they'll tell you to not expect fish much over 30", although there will be a chance to catch bigger. Is this from overfishing? Yeah probably to a certain degree but I think the law of averages comes into play as well. Not every fish is going to achieve the max sizes listed...even with perfect conditions.
2. From what I've been told by Japanese hobbiests that have kept these fish for years, the coloring stays nice like this into adulthood with this variety. It's one of the things that seperates it from the more commonly seen 'Great Nile Perch'.
3. No, it's not an all new
L. niloticus, as I mentioned, it's been kept in Japan for years...probably here in the states as well (just like most of the 'new' fish out there), I think this particular variety can be kept quite well in aquariums yes.
I suppose you could compare the 'Congo' Nile Perch variety to the 'Regular' Nile Perch variety the same way you could compare the Northern Largemouth Bass to the Florida Largemouth Bass...pretty damn close to the same fish but there are some slight differences...one of which happens to be a genetic predisposition to size and another to color/pattern.
I want to mention also that IME most fish
slow at a certain size...from what I hear, these fish
slow at around the 24" mark...doesn't mean they stop growing or max out at 24"...just that they slow.
