Okay so ill keep this short...I have a srd monster kok fh baby...around 1.5 inches long...i bought him a couple of days ago...he was just doing fine untill 2 days back when i changed the position of my tank...so the earlier tank was completely dependent on sunlight for illumination.there was no background in the tank.and also the tank was in a secluded place...on its new place, the tank is well lit, has a black background and is kept in open space...and my fh is extremely stressed out...all he does is either hide behind the filter or sits in a corner...also hes tilt-swimming a bit...there are vertical stress lines on him and hes turning greenish...should i be worried? cus its been 2 days this is happening.
