I just acclimated a few swamp darters and sheepshead pupfish, only to find out that they are incompatible. Apparently, the darters are shy and peaceful fish, while the pupfish are a bit boisterous. To avoid any fatalities, I am selling the pupfish. They are available for local pickup in Bayside, Queens for $18. Please disregard the other thread where I listed the 3 darters, as I decided to keep them instead.
