Healthy fish means no ick !! read...
i started to get ick a lot...and started to do this....
IT WORKED...without any stress at all to the fish !
a little piece of garlic...crush with back of knife..get the juice off the knife onto finger and massage into the food (i used flakes) every other day !!
thats it...no ick !
it builds the immunity in the fish ..and the ick has a real hard time attaching itself !
if this is done regularly enuff..u will have good looking..healthy fish !
you can do the same with garlic oil too !!
this worked wonders in my tank...and the ick stayed away...
