I have an Amphilophus Sagittae tank boss in an established 300 gallon community tank that spends a lot of time sitting on the bottom. He also seems to struggle a little bit when he's not on the bottom. He will swim around a bit then almost "crash land" to the sand. The water has always been pristine with two 30% WC weekly.
Has anyone seen behavior like this before?
