Howdy, first time poster long time reader, here with a strange situation. My res is Bout 7 months old and so far every thing is well, he eats well and bask well, but for the past few weeks or so when I turn off his uvb lamp at night *leaving the heat lamp on.* He goes into a type of exploration mode climbing onto his dock and crawling around every nook and cranny. Each exploration session last about 3 minutes, he'll dive back in the water, then try again after about a minute. And this goes on for about an hour until he stops trying to do it.
Most of the time during his little exploration sessions he likes to climb on a rock I have for him up there, but he'll usually crawl around the whole place.
