my betta got ick from a filter i used i guess i didnt wash it well enough, so i put him in the little cup and put a little bit not even 1/10th of a drop of quick cure and i put him in a heated tank in his little cup and 3 hours later and hes laying flat at the bottom of his cup.
(please no scolding or negative anything hes my favorite and im already feeling bad enough to know i possibly killed him)
i saw that the ingredient on quick cure was malachite green and i dont know what to do, is this a wait for him to die or can i do something?
please help and thank you in advance
