Hi. I've had this guy for about four months. Was doing great, but a while back, it looked like he was going to split and then changed his mind. So now his foot looks like more of a bridge. And I just woke up this morning to see that his left side tentacles have these black streaks and I'm wondering how worried I should be about this guy. I recently reduced the time my lights are on from 8 hours to 7 hours while trying to battle some dinos. Parameters are all in good shape. Any thoughts? Thanks.
