The more I look at the geophagus, the more I like them, I've been eyeballing the ones that max out at 6" or so, like the tapajos or the pindare.Typically rams get to around 2", which isn't much to a fully grown bichir. I personally wouldn't do it in the same tank. they could become a $10+ snack if they swim too close to the senegals.
Earthearthers/Geophagus might be a better option.... but some grow past 8inches. Not sure about their temperament though. We'll have to see what the experts say.![]()
