I have a cherry barb in a 20 gallon tank who is beating his front fins frantically and swimming upward in order to stay up, otherwise he sinks to the bottom. It seems like his swim bladder isn't working and he can't "float" in the water like before. I've had cherry barbs die of this in the past (2 years ago), and I never knew how to help them or even why they got it. Can anyone tell me what this is or how I can cure it??
The only difference in tank parameters is that the ph has risen from 6.0 (measured on 7/16/16) to 7.0 (measured today, on 10/5/16). This could be the cause, but in the past fish had this problem without major changes to the PH so it could be a coincidence?
I did a 50% water change and am going to feed him peas, but what else can I do
UPDATE (same day): Fish happily devoured peas, Looking at him up close it seems like his "chest" area is a little bloated looking, but otherwise looks normal despite the fact that he seems stressed and is struggling to stay "up"
UPDATE (10/6/16): He seems even more stressed, darting around when I get near, back arched. I didn't feed him today because I heard fasting can help, is that true?
