any idea what these guys are? We just got them in at work and i love them.
The two greenish cichlid-esque ones are baby sunfish, nearly impossible to tell what kind they are at this point. They’re territorial as adults and will get at least 6 inches long, so they’ll need a pretty big tank, or need to be taken back to the river and swapped out for more babies when they start to mature. The smaller ones with the flat head tops are gambusia, aka mosquitofish. The ones with orange fins are, I think, some kind of shiner. They need to color up some once they get more comfortable. More cover would help them color up slightly, like some shelter at one end of the tank, but they need lots of room to zoop back and forth. They also need plenty of oxygen, you usually find them in fast-moving water. Try adding some sticks and driftwood in, everybody involved will want plenty of space to hide.
