My clown loach is swimming vertically under where the water from my filter drops back into the tank doesnt seem weird until i say that it does it almost all day!!! unless i go over to the tank and then it swims away...
Only thing i could come up with is that she/he might be lonely because she had a friend and they always use to go everywhere together (around the tank
) until the other one died when the bushfires went through 
any ideas?
