A couple of questions!

[F.H]

Yeah, well I initially got the fish, started prazipro on the second day, did 2 treatments of prazi back to back so, 2 weeks.

Then I just observed them for 2 weeks, as they didn't show any signs of ich/disease, and I was about to put them in my display when I decided to do the tank transfer treatment prophylactically for peace of mind before putting them in my display.

The tank transfer is pretty much done now, and I should be putting them into my display tomorrow, but I figured I should ask about these two things before I do.

It's just curious, because in the past when a fish has gotten stringy poop like that, it continues to have it until I treat it and fix it... but this time it goes for days with normal poop, and then one day might have poop similar to the one pictured, and then go back to normal poop.

Shouldn't the 2 doses of prazi have been enough? should I medicate their food with metro instead?
