Hi thanks everyone. Their tubs are kind of on the tall side rather than long.but they seem to be happy. So far every night they are on the move testing the lids and doing laps around the tanks. Took them out tonight and stimpy seems to be the "layed back and hang out one" Ren on the other hand is kind of jumpy but settled down quickly and wanted to explore and watch every thing. So different from my corns in personality so far. But they are fun. I am really enjoying them.
