He's about 8-9" TL. He is in a 180g planted tank along with another one his size and 5 juvies, plus some Columbian Tetras and a ton of corydoras. A pair is good in a 60g. They need fine sand, to sift. Nothing abbraisive. I use 3M Colorquartz, which is a pefect product for them. They are 100 non-aggressive, and are very shy. They are also not easy to obtain, mine are wild stock from an importer in Florida, fishfarmUSA. Most of the Suri- race geos sold in US are mass produced, who-knows-what species that never get to look like that. Dont buy the LFS geos, get them from a breeder or wildcaught.
