I'm just not going to buy any more fish


I went though a case of Ich ,and did a kick-Ich treatment and waited three weeks not seeing any sign of it ,all fish looked good ,been on top of water changes , testing water , temp everything I can think of .
I picked up a coarl Beauty, and bam!! two days he's got it all over him

. All other fish look good and no sign of it on any of them yet .
I'm really bumed out
