I’ve had a ten gallon tank with one Blue Gourami for awhile now. I bought 2 neon tetras two weeks ago and just introduced them about a few days ago. I noticed that the Blue Gourami has been chasing them and harassing them. I thought it would stop if I re-arranged the tank and gave them a bit to get used to each other. However my neon tetras hide behind my filter and just look miserable hiding from the Gourami. How do I make them get along? Should I buy a few more neon tetras? Keep in mind I only have a 10 gallon.
