I have had 1 gold gourami in a 10G tank by himself for about a month because the second one died a couple of weeks after I bought them both. SO I bought another one today to put in with him and minutes afterward the current fish started beating up the new one. It was bad. Wouldn't let the new one sit for a second...literally! Is it just because he's been in there so long by himself? I know the tank is too small for when they start growing towards their max 4", but I can transfer them to another tank in the future. Any help would be great.
