I already posted this in the New Reefkeepers forum but I thought I would post here also to get more opinions. I have had my puffer for about 3-4 weeks now and he usually spends about 90% of the day swimming, occasionally resting on the bottom. For the past two days he has been laying on the bottom of the tank the whole day. He comes up to eat and that is about it. He swam maybe 5 min all day today. Is this normal or is something wrong? He still eats good, he is just not swimming. He did eat a little more today than he usually does.( I accidentally put a few more goldfish in the tank than I thought.) Would that have anything to do with it. He usually eats two a day, he might have had four today. He wasn't swimming a lot yesterday but more than he did today.
