How big do geophagus red head tapajos get?

[poly-nomial]

to keep with the bichirs in a 55g, id go for a sax species of pike

I was thinking of pikes. I might go for them. they are more "oddball"

They can get up to 8". Haven't seen any 10 inchers but can't say they don't exist

IMO 55 is long enough but too narrow for a group of adults. The extra 6" in a 75g makes a big difference. But of course, the bigger, the better.
