Alright so we just recently traded out a small fish in our tank. The person took the fish home and treated for worms and said they saw a couple good round worms come out. Does this mean all of the fish in our tank have worms?! If so we could tread with the prazi pro or whatever it's called. But can you treat the whole tank with that (a 250gal tank) or do we need to take the fish out 1 by 1 and treat in a hospital tank? All of our fish are between 10" and 20" so that would be really difficult. Also, if we have to take them out one by one wouldn't treating them and then throwing them back into the infected tank just not work? If that makes sense?
Thanks!
Thanks!
