Bought two very small RES....the size of half dollar. Have had them 5 for days and one is very aggressive to the point of pushing the other out of the way...walking on the other to get to food. Meanwhile the other stopped eating and just sits in her/his shell....either on a basking rock or in the water. Water temp 82...basking light and uva/uvb light...and filter. Have light on for about 12 hours a day. Problem is the one that is in the shell. the first day or two it ate fine...and then it stopped and has been in its shell. I tried to feed it outside of the tank away from the aggressive turtle but it stayed in its shell. I put it back in the tank on a fake floating island and it stayed there in its shell all night...thought it was dead....but my son and husband dripped a small amount of warm water from the tank on the turtle this morning and she/he got off the island and swam, but then held onto a real rock and just floated. He swam about two hours ago...got pushed out of the way by the aggressive turtle turned upside down..did not right him/herself..so i gently picked the turtle up and put it on the basking rock where it is right now.
Any thoughts would be appreciated.
Thanks in advance
