"The Mega Megalodoras race, who will Irwinni?"

[jlnguyen74]

Mine... Took one out to measure last year, and he's the 2nd biggest. Biggest guy probably 22"-24"

What's their growth rate in your experience?

Slow... Like 2 inches per year. I have them for 5-6 years, when they were 10"-12"

Thanks! Sounds about right. Well, there you go fellow participants. Let's revisit this tortoise race in, shall we say, 3 years?

BTW, Jlnguyen reports a marginally better growth rate of perhaps 2.5"-3" a year for the pterodoras granulosus - from 8"-10" to ~26" in the same 5-6 years http://www.monsterfishkeepers.com/forums/showthread.php?607985-PTERODORAS-GRANULOSUS/page2

Well, I have held out for 2 out of the promised 3 years

My 6 guys have mostly been in 4500 gal and poorly eating except for one so I left it in 4500 gal. It's probably about 18" now. The rest are back on a 240 gal and don't look like they grew to any significant degree, perhaps an inch, maybe two for a couple specimen.
