Ah interesting!
I love any species of geos, these seem like they're a really good species to have, a lot of personality in these little buggers.
Long ago I had 1 in a 55 that grew to about 6 or 7 inches in 3 years, he grew these really long fins and was one of the most beautiful fish I've kept. He was kept with small ATFs, Tigrinis, flower horns and everyone complemented the geo.
