my gbta was badly bleached 2 months ago when i bought it, since then i have been feeding 1/2 a silverside a day and it seemed to be doing well, fully open all the time (mouth closed) and taking food. now it does'nt look so good. keep moving to the back of the tank is'nt open much and mouth is sometimes wide open and takes food but then spits it out. my water params. are all perfect plenty of flow in a 20 gl with 2 emperror 150's 2 maxi jet 100's and a protien skimmer. i do 15% weekly water changes with ro water.. and i have T5 light kit (dont remember the watts, but know it was for a 20 gl) im not sure if this is something i caused or if it was dieing when i bought it... any help would be very great . thanks in advance.
