I have been treating our guy Feathers for SBD and he is scheduled to be done with treatment tomorrow and return to his tank but the past couple of days I have noticed that instead of looking like a round or oval-ish ball, his poop looks like a long, thin piece of string. It seems to be about the same amount of waste as usual, just in a different shape/form. I am wondering if something is still bothering his insides because right before he poops he is relatively inactive/slow and just after he makes waste he becomes very active, as if he is suddenly feeling a great relief. What could this mean?
For the SBD I have been using Epsom salt 1 tsp/G and fasted him for 4-5 days initially but he is now eating 2 pellets/day (1 morning, 1 night) and has been pooping pretty regularly - at least every other day but mostly every day. I was meaning to try to get some frozen daphnia but with the thanksgiving holiday things got a bit crazy and I never got around to it - should I still try to see if that would help him further?
I feel bad that he has been in a QT tank for most of the past 2 weeks and would really like to return him to his 2.5G but I'm worried that maybe he's not all the way better yet....
ETA: I neglected to mention, I have been doing 100% daily water changes while he is in the QT tank.
