spotted turtle
n.diamondback terrapin (cbb in freshwater)
eastern musk turtle
reeve's turtle
HAVE KEPT ALL OF THESE.. and bred the spotteds, terrapins and reeves
spotteds live in very shallow water - poor swimmers.. more terrestrial than you might think
diamondback do much better in brackish water - need lots of water to swim in with basking spot
musk turle - bottom dweller.. also poor swimmer
reeves - poor swimmers.. not big baskers
you could keep all but terrapins in water with lots of plants, etc. so they could climb to surface to breathe / bask
