Anyone have any experience with these? I need to get a couple more corys for my 15 gallon and for some reason I haven't been able to find any more c. trilineatus lately. One of my LFS had a few of the c. virginiae and I thought they were pretty and a little less common. Does anyone know if they are a hardy type? Also, are they on the shy or outgoing end of the cory personality spectrum? Thanks!
