Oh. I've just bought 5 tiger barbs for my community tank. I did have only 3 but one kept bullying the others so off I went to buy 2 more...
They leave my neons alone, but they do seem to 'wrestle' with each other. And my goodness, they eat.
I had a 10 gallon with barbs and cardinals, I forget the exact number, I think 4 or 5 barbs and 6 cardinals. It was a planted tank.
They got along fine but I had well water at the time and struggled with that, also people didn't test parameters as much as now, I focused on pH and hardness.
The tank was in my bedroom and I could see the shadows of the barbs "mock fighting" or whatever they were doing.
I worked long hours of shift work and after fussing for a few years I was remiss with maintenance and everyone died.
But I'm back, on city water, armed with my api kit! I have a 10 gallon with Betta and neons and I'm setting up a 20long. I was thinking neons and shrimp but a tankful of barbs would be near too.
Barbs and Cori's?
