I'll be upgrading my grow out tank for a colony of small gibberosa within the next 1-2 months which will leave me with an empty 125 gallon tank. I was thinking of selling it, but now I'm thinking I would like to keep something in it... I was thinking maybe a breeding pair of some south American/ central American cichlids (that would produce fry I could sell or at least give away), a mixed cichlid community, or really anything else...What would you do?
