My three-spot gouramis are chasing my new glowlight tetras I got today. We asked for 10 tetras but I can only count nine, so I have 9-10 of them. My tank is a 36 gallon. I have 3 three-spot gouramis and 7 bronze Corydoras in addition to the tetras. I might get some more plants for them to hide in. Should I add more glowlights?
