I just moved Miles from a half gallon tank to a 5 gallon tank with a filter about an hour ago and I was wondering how long it will take him to settle down and get used to the filter and the different buoyancy in the water because of the filter. He is currently swimming around a lot, I'm assuming because he is amazed by all the space he has to swim in but I noticed that he seems to feel the push and pull that the filter makes. Will he adjust to that? Also the filter is making some bubbles so will those affect any bubble nests that he makes?
