Hello all,
So, today i bought 2 pearl gouramis. The shop owner, who set up the australian parliament aquarium in Canberra said that they are two males and that they are peaceful. I introduced them to the tank about 4 hours ago and since then, at least one of them has been chasing my neon tetras and some of my smaller guppies. Also one of them has been moving actively, but has about 2 minutes every so often (not sure, have only seen him do this twice) when he just sits just under the surface and starts gulping down air. Is this normal behaviour?

Also can someone tell me what they think of the Pearl Gourami and what they eat?

Any answers would be appreciated
