Think biggest I seen was 3'. Don't think they're comparable to snakeheads and wolves...Yeah definetly! Also this Giant ansorgi looks pretty nice, i guess a congicus at this size would have feature a little bit broade skull, but be less thick?
Still there has to be the one monster bichir somewhere!

I believe it was 27"+ in 2012.There are home aquaria photos of some congicus in Japan over 30" mark. Just haven't looked for them yet, lol
For all who is seeking motivation for their growout, or planning. Here's fellow mfk member C CDM . It was 25" in 2010. Got it at 7" in 2003. The possibilities... Wonder if it's still thriving.

I remember now. His tank crashed in 2012. Majority of his fish died including his red aro and monster bichirs. I believe only 2-4 of them survived.Correction on my previous post. It was 27" in 2010
C CDM any updates?
