At home with The Eartheaters?

Those of you who know me well are aware of the fact that I tend to favor small, relatively docile fishes, like characins- the "Teacup Poodles" of the aquarium world.

Well, I may favor those fishes in my tanks, but I do have a healthy respect and admiration for some of the more- shall we say- "hardcore" fishes...like the so-called "Eartheaters" (families Acarichthys, Biotodoma, Geophagus, Guianacara, Gymnogeophagus, and Satanoperca). This lively and diverse group contains some of the most endearing and interesting cichlids around. With a surprising number of our customers wanting to incorporate botanicals in setups with these fishes, I couldn't NOT take a little look at them in "The Tint", right?

And of course, the name of the genus Geophagus contains the Greek root words for "earth" and "eat", as if to reinforce the popular collective name. So, in case you haven't figured it out by now...they dig in the sand to get food...oh, and they poop.

A lot.

But you probably already knew that, and I'm the last guy you really want to write one of those "Review of the Eartheaters"-type articles, so we're going to focus more on the kind of environment you'd want to set for these bad-asses, from a botanical perspective, of course.(click to read more)

Geos are some of my favorite fish!

There's a 75g in my fishroom with 5 adult Gymnogeophagus balzanii that we collected in a lagoon in Bella Union, Uruguay. They spend all day displaying for each other between sifting through mouthfulls of sand and decomposed leaves...

I'm falling in love with their charms, as have many of my customers! They're ridiculously endearing! Have any pics from your collection trip? Would LOVE to see some biotope pics!

I'll find some from my prior trip to Bella Union, Scott. This trip, the water was much higher and it was hard to see much.

In a nutshell, balzanii live among branches of submerged trees. The substrate is pretty muddy.

Our guide Felipe, had me wander under a big clump of trees to flush them out so he could cast net them. Nevermind the caiman and piranhas :)

So Tony took a picture of one of the big male Gymnogeophagus balzanii that we caught in Bella Union...and the little pond where we caught Apistos and Cichlasoma dimerus (and Cory cats and tetras and knifefish and Hoplo cats..) buy still looking for pics of the balzanii habitat.

By the way, the balzanii from Uruguay are way yellower than the ones that have been in the hobby (from Paraguay). "Rio Uruguay F-1 Balzanii" were available on lists a couple of years ago but didn't turn out to be the real deal (I spent a couple of years growing some out...before collecting some real ones myself)...
