I went into my room a few minutes ago and found my pearl gourami dead! And hour ago he was fine swimming at the top, he just came out from hiding too! I got him a few days ago, he is in a 29 gal with 2 odessa barbs and 3 julii corys. I have plenty of live plants and hiding places. The "skin" around his head was black, was this a sign of disease? Are these fish hardy?
