Ditto with Barb. My Gouramis are generally very peaceful, but they like to review the pecking order after feeding. My 'Fire-Honey' Gourami, which is a variant of a honey gourami, is by far the smallest of the bunch, but also the most aggressive. Overall, though, they are the most peaceful larger fish I have ever kept.
