Hi! I bought my first school of fish for my 55 gallon tank last night.
I got 6 Neon tetra. I acclimated them and then let them go in the tank. They stayed in a tight little group and explored the tank for a while, swimming around its borders. But eventually, they all congregated in the area near the middle at the bottom and have been swimming around in a tight little group, but don't leave that area. It's not like they're hiding because I have a pretty lush area of plants on the left side and some rocks and a smaller plant on the right side, but they're staying right in the middle out in the open. It's weird for them to be at the bottom of the tank too, isn't it? They were the same this morning just swimming around, barely, in their little group, in just one area like none of them wanted to take the lead to go anywhere. I actually couldn't find one of them last night before I went to bed, but he was back with the group this morning.
So, why are they acting like this? Is it just because they are in a new environment?
