One of the babies turned out to be a belly slider but the other four are normal. The female looks like she is in distress… or there are more babies coming, (probably both!) I think I can see the eyes of another one near her vent.
Further reading on this fish points out that if the female is pregnant and moved, she will drop her babies prematurely and both the babies and mother will die. This may or may not be correct but I won’t take a chance with this few fish.
