Okay this isn't about betta, but it is very important.
Whenever I buy guppies from petsmart, One of them has fish tb and wipes out the whole tank to I have to start over.
I treated the tank with kanamycin and for a few month everything looked fine
but today I noticed that one of the guppies was really pale and wasn't really playing with the other guppies.
He would kind of hang out to the side of the tank at the top away from all of the other fish
He doesn't have a curved spine yet, but it looks like it may be starting
I stuck him in a jar, but he is actually really active. When all of the other fish that had tb were in the tank they would be really inactive, but he is super frisky.
Does anyone know if this is tb? or am I just over reacting?
I realllyy dont want the whole tank to have gotten it
edit: He also has a really thin tail. All of the other guppies have thicker tails but it looks like his tail is really thin and it kind of looks like its deteriorating
