I have an ick question, so I figured I'd put it in the same topic.
I got back from vacation to find my fish with ick. I have five black tetras and a betta. Since I have to put in half the dosage for the tetras, would it be better to put in the other half of the treatment later that day for the betta or not do that at all? Also, should I leave the aquarium light on or off. I haven't found answers to these questions anywhere, and my roommate and I have looked all over the internet.
