Diamond Tetras aggressive?
Looking for some advice from someone who keeps Diamond Tetras.
We have had our planted tank for six months now. Currently holds 5 Diamond Tetras, 5 baby diamonds (they recently bread), 12 neon tetras, 6 amano shrimp and most recently 6 Otos.
My question is, are diamond tetras aggressive fish? Since we have had them we notice that they do move around the tank quite arraticly sometimes. Over time, we have noticed that our neon tetras donít always come out of the plants much and we wondered if it was to do with the diamonds. In addition, we added some Otos yesterday and they do not seem keen on the new arrivals. Although they havenít done anything to the otos they seem to be circling them quite a bit.
We picked diamonds as we believed they would be good beginner fish. They obviously seem happy in their environment as they have recently bread. Should we be worried about our other fish?
