I'm setting up an 8ft 240g and trying to decide on stocking. I can get my hands on 6 or so G. cf. brasiliensis and I was wondering if anyone had any long-term tankmate suggestions for them, as I know they are more aggressive than your typical geo. I currently have 5 Heros sp 'Inirida' and 5 Archocentrus centrarchus and a group of Colombian tetras. All are 2ish years old but I'm not set that they have to live in the 240. I could keep the Heros and rehome the centrarchus and go with an SA tank or I can do a CA/SA mix but I am not open to mixing continents. Thoughts or advice? Thanks.
