Fighting due to overcrowding help

[ZooKeeperLJ]

So It's been a while since I've played so this could be me being dense. Got my zoo, have two Jaguars, one male one female. All green for space, climbing and water. Green for enrichment, plants and everything else but they keep trying to kill each other and the game says it's overcrowding?

The habitat is too small when that happens.
What does habitat size say? Green as well?

Or do you mean green for space on the first tab?
It should also be green for size.

Tip: Screenshots can be very helpful in these situations.
