So i got 4 guppies yesterday and started my TSS+ cycle and one of my guppies seperates himself from the other guppies. Now my other guppies do the same but go back to their little school. This guppy rarely hangs put with the others. Which really is not a problem since he might just not wanna hang. But i noticed he does not have great coloring and has torn fins. Either he was nipped a lot in the tank i got him from at a very good LFS or it's finrot. Now i don't think i can actually treat it because i am doing a TTS+ cycle and i don't want to mess with or kill the bacteria. Could it also be that this guppy could be sick from either nipped fins or finrot? Here is a pic below.
