Hi all, just wondering what people's thoughts are on how many schools of tetras to house in 140 litre planted tank. I currently gave 10 neon tetras, who were swimming very calmy at the beginning, they were the first fish I got. After a week I added 6 black eye tetras, both schools stayed within their groups. Then a week later.... added 6 rummynose. 1 died overnight. However, last few days the groups are all intermixed, darting more. They look like fish on speed! Have I overpopulated the middle region of the tank? Looks a little messy. Also have a bristlenose and golden gourami ( who hides most of the day, doesn't bother tetras). Ph 7.4, ammonia 0 - 0.25 and nitrate 0.5.
Will enjoy hearing people's thoughts
