I have dosed praziquantel for my 10 + 5 gallon aquarium which are connected together with a pipe, i wanted to know if I could treat 1 dose for a week and that if I have to fast them for a whole week or would it be ok to feed them after 2 days of the first treatment and then dose the second dose for the secondth week, i am currently treating a zebra eel aswell as a greasy grouper, my grouper seems to be still aggressive eating in the third day of the treatment whilest my eel doesn't seem to have an appetite
