i got this clown marron clownfish, basically for free when i purchased some other dried goods... and was told that he lies to just lay on the sand, which sounded a little weird... but i was cool with it.
so after few days here, he still lays on the sand, sometimes even sideways, he appears to be weak, even though he eats, but while trying to swim to reach the food, he just seems weak. his fins are either beginning to rotten or nipped not sure how to tell the difference. so he swims across the tank every once in a while, but goes back to the sand. he is quite small maybe 1.25"
what can I do for him? or is he ok?
