I just received my Mardel Maracyn Two medication and API Stress Coat in the mail the other day. I'm keeping my betta in a half gallon tank as his quarantine tank.
He just recently made a bubble nest, he's eating, and he's happy when he sees me so his behavior hasn't changed. His tail fin has chunks missing but it looks as if the tail is slowly healing. I can't tell for sure.
The Maracyn Two that I got is a powder packet with 8 packets in each. It says to put two packets in for every 10 gallons. Since he's in a half gallon, how much should I put in? A small amount of powder less than 1/8 of a teaspoon?
