I knew you'd know who I meant. lolWell said, neutrino. And I agree, I wouldn't take his advice on nutrition either. lol

So you prove my point. The Internet care sheets did not give you sufficient information. You had to "dig"Trying to find reference for the size given on seriouslyfish and fishbase, lol.
I think it is taken from the catalog of the fresh water fishes of Africa.
Link: http://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers13-06/15357.pdf
The maximum size of p. senegalus recorded in that catalog is 505mm and the maximum size of senegalus meridiolUllis, which some think are the same fish is given as 700mm.
After digging some further info, I found the below paper referring to the 700mm size in catch 31 and 39.
Polypterus senegalus Cuvier, 1829 Site 20: SL 224 mm: 1975.6.20.11. Site 21: SL 220 mm: 1975.6.20.12. Site 22: SL 270 mm: 1975.6.20.9. Site 24: SL 215 mm: 197 5.6.20.10. Site 25: SL 212,215 mm: 1975.6.20.13,14. Site 27: SL 255 mm: 197 5.6.20.8. Site 28: SL 215,220 mm: 1975.6.20.6,7. Further specimens up to 700 mm SL were caught at sites 31 and 39, but not retained.

Then researching some more, I found a paper on growth of senegal bichir(below) Maximum growth observed for a 7 year period was 265cm in females and 255 in males, females apparently growing bigger than males. They also stated that the growths observed in laboratory settings were strongly inhibited compared to those in natural environment.

My take on that limited information is that they may grow bigger in nature, as recorded by river sampling, that their growth is inhibited in artificial settings and that most fishkeepers may have to keep them alive for much longer than the 7 year period in the paper to be able to judge maximum growth of an adult.
Also,common fishkeepers may be correct in saying that senegals don't grow bigger than 12 inch in aquariums but that opinion has to be challenged by keeping specimens alive for many years in larger aquariums and suitable environment.
Good point about captive breeding. The size issues are one thing but almost every bullet point in those links has inaccurate info. Things like polypterus not accepting dry foods (pellets) is flat out nonsenseLet me chime in on this, most of this care sheet only talks about wild specimen that they caught and take care of or did a study on and that was back who know how many years ago. Do this people ever updated a care sheet? Most fish that we get at our LFS nowadays a breed in captivity, alot of fish are being inbreed so growth,lifespan and genes decrease.
I picked that one because that's the one you started finger pointing at.Your stuck on the size of sen's... thats the tip of the ice berg.
Ain't it the truth. There are enough things I've been told about fish, only to learn otherwise over time, sometimes opposite what I was told.I personally value the experience of others, but when that information is first hand source, not a word of mouth as it normally happens. Too much wrong info has been sang as gospel over the years and some people do things just because others do them that way, not for any other good reason, thus contributing little to the group experience.
Yes, agree. But you know it is incorrect because you've done your research, not because it was posted on seriously fish specifically.This is just a few examples of how incorrect info gets posted on the internet, and people run with it.
The difference between your posts and some other people's posts is that your information is well researched and well explained and is also verifiable. You also provide your sources where applicable.The last count that I saw posted was approx 50 million (possibly more) being exported annually, and the vast majority of those exported have always come from Indonesia (Kalimantan Provinces) not Sumatra. The reason for that is due to the Kalimantan specimens overall brighter, more colorful markings. This was mentioned several times by an MFK member who lives in Indo, and who worked in the aquatic trade. You can find his comments in my sticky on the two different geographical variants, as well as in the Clown Loach breeding and export study sticky. And while this species has indeed been bred in captivity, even in commercial circles, it is far too time consuming and labour intensive (at least thus far) to supply any real quantity to the trade. Certainly not enough to compete with wild specimens.
