So I have 3 Zebra Danios in a 29 gallon that is cycling. They've been in there for a day and a half now, and I noticed that they seem to like staying under the filter for long periods of time. Yesterday, the smallest Danio spent around an hour or two just hanging out under the filter, then the second biggest decided to join it shortly after. Today, the biggest is staying under it right now and looks like it's going to spend the night under there. Is staying under the filter comfortable for them?
The filter is a Fluval C3 power filter, so the stream of water coming out is pretty strong and makes some bubbles, which they seem to like trying to eat, and I also have two airstones which makes the water move a bit.
