i have 2 oscars and i was planning on adding a clown knife today.. however i woke up this morning and my oscars had ick (maybe a sign they dont want anymore fish to live with
)... so i treated them and followed the advice on this site (thanks!) when it clears up how long should i wait before adding new fish?
