Alex, you're not going to believe this. I've never seen this before with dats. I've had them less than 2 weeks and the NGTs are already coming up to the front of the tank to greet me. I was spellbound and couldn't think of anything but sitting on a bucket and getting to know them. What makes this more unusual is the fact that, because of the number of tanks I maintain, I never tend to spend enough time on a single tank for the fish to get to know me. Thanks again for this awesome pair!!!!
The Mbus aren't coming up to greet me yet but, they've finally stopped running for cover when I approach their tank. I'm hoping for puppy dog behavior in the very near future.
