I know some cichlids don't mind being the odd man out while some
prefer the company of their own species. Which category do Geo's
fit into? I used to have 2 but one died a while back. The
remaining fish seems content to move all my gravel around all by
his (her?) lonesome. Should I get another one?

And if it is better to have more, are they picky about whether
they're male or female? 'Cause honestly, if they don't have a
sign saying 'I'm a boy' I have no idea.. And from what I've
read, Geos are hard to sex anyway.

Hello,

The current scientific name is Satanoperca jurupari. According to
my book on South American eartheaters, all members of this genus are
best kept in groups. However, my experience is that they do okay as
individuals if need be. But the optimal would be to purchase
several more with, assuming the size of your tank permits this.
Also, it would be preferable to have some type of small grained
gravel or coarse sand so your fish can sift this through their gill
rakers -- a behavior that is unique to this type of fish and very
natural to them.

Regards,
