No, nothing to do with the day, time or not much of a pattern at this point that I can tell. Also I have built more then a few caves and places for her to get in and hide. I have had drift wood spots that he could not get into that she would dig out for shelter and sooner or later he scares her out. He will get in some small places that I would not think he could get. He has knocked rock "caves" apart, he will find little spots to get in far enough to ruin her comfort level then she will flee that spot. That is another reason I think things might work out better in the 360.....I will build a deep large "cave" for her to get away into that he WILL not be able to poke into and make her flee. She will hopefully trust that he cant make in there or break things down. Also they had a great bond for 7 months or so. No hiding spots or spousal abuse.
Have you considered customizing a 3D background for your 360g? It's hands down the best escape she utilizes so it may be an idea for you. Also you can keep cutting them once installed as she grows you can keep up. I will be doing another background for thier next tank.
Beautiful pair. You should be ready and record a video of it next time, it sounds really interesting. Never heard of anything like it before.
Thanks. Every time I've seen it (twice) I start banging on the tank to make him stop. All other times I've just seen the shark bite injury so I know it's happened again.
