Hi,
my silver awowana was in a 200 l tank and he was moved to a big tank last week we took all the water gravel into the new tank. he stopped eating and has spent a lot of time sitting on the bottom. he swims around for a little bit then sits on the bottom some more. he faces the glass every time if that important? the tank is acrylic. he stopped eating for a few days and has started eating a little but not like he use to, my clown knife has gone into hiding and doesn't eat a lot either but my black clown seems normal not that i have ever seen much of him. my pleco is happy ive seen more of him since ive moved him. i brought a pair of small red should severums and they seem to be fine. are my fish sick? all the water is ok it was the same as the old tank. also is there any way to get my clown and black ghost to come out more?
