i got my jar in my 180g i justed added a wet dry with a fx5 got out puts pointed to top of water. i took the air stones out now my arrow is just layin down
the water is good tank been running a month now.i did my weekly wc wen i added the sump i took the stone out cuz i read that with a wet dry you wouldnt need the air stone now he r she is just layin on the bottom movin my sand
try poking her till she swim back up..happens to mine someitme... but if you change to a new tank with new water best you pray she survive or use water conditioner at least....
new tank stress arrow hard.
if ur just replacing osmething .. probably just scared happen to mien most of the time lol
