If he's the "king of the roost", he's probably just expending a lot more energy than the other new ones making sure they know that. Angels can have very singular personalities like any other cichlid and that can make one more sedate, aggressive, big eater etc. I think you're fine from what you've posted. Not knowing what the relative sizes are for all 7, keep in mind that aggression can become an issue in that size tank. It may not manifest itself at all, but it's a good possibility as they all settle into the space. And that space may end being a little tight for all 7 at some point for them to grow to proper size and shape.

He definitely is the king of the tank. He is also part of a pair. Im getting a 75 gallon tank at the end of the month to accommodate the 7. The sizes vary from quarter size the the alpha and hes not quite as big as the palm of my hand

 

You're very welcome. That's a pretty big size range. I'm pretty certain that one or more will get the short end of the "Size Stick" and remain on the smallish side. If you can pull it off, consider running both tanks (I know, easy for me to suggest) and leave the pair in the 56. You should see more uniform growth from the newer ones and they would stand a much better chance of getting to the size of the alpha male you have now.

It kind of goes along with what happens when you raise an entire spawn. They just don't grow at the same rate. So that if you have the time and patience to split the little ones that are visibly growing at different rates, you'll find that some of the smaller ones will "catch up" when re-homed. It's an issue of metabolic waste.

 

Thanks angelo
Unfortunately im trading the 56 for the 75. The good news is that none of the angle like the same food so they all get plenty of food ;-)
