Hello
I just setup a new 55gal tank last week and added 4 small fish to it last night (2 Fancytail Goldfish, 1 Common Goldfish, and a yellow Koi). I have two long horizontal airstones on either end of the tank and a large Ehiem ECCO cannister filter which produces a strong stream of water horizontally along the top/back of the tank.
The fish seem to enjoy these strong currents of water. They will swim quite aggressively up the stream from the outlet of the filter, then ride the current back and start over again. The little Fancytails look quite amusing as they waggle like crazy while the torpedo shaped Common and Koi seem to do it quite effortlessly. They will also swim down the curtain of airbubbles from the airstones. Sometimes they will swim with just enough effort to stay motionless as the bubbles rush past them. Often all four will be in the bubbles at once.
Now, I'm new to Goldfish so to me it looks like they are playing and having a grand old time. It's fun to watch. But I don't know if maybe this could be some kind of abnormal behavior. I read somewhere that Fancytails are inefficient swimmers and can be stressed by schooling with Comets or Common Goldfish. But these two seem to do it even if the two streamlined fish are off doing something else.
Has anyone else seen this kind of behavior?
Thanks,
Dave
