I have a group of F1 gymnogeophagus balzanii from the Bella Union Uruguay location where their parents were caught. Pretty simple tank setup so far in this 90 gallon. I'll be adding a group of F1 cichlasoma dimerus to this tank as well where they will grow out until they're moved to a 180 I have but can't setup until next year. I've really enjoyed watching these guys grow so far. Got them a few months back when they were just tiny little 0.25'-0.50" fry. They've put on some good size so far. Hoping I'll get a pair, thinking I will.
