I have had my betta for 6 days now. With the first three days spent in a Gal. bowl. I moved up to a 5 gal tank with a Tetra WhisperMicro filter and a heater. The temp is between 76-78. (The thermomater reads in incrimints) Also, there are two plants in the tank. The tank was filled and running for 24 hours before I put the Betta inside. Used a bag and gradually added the new water to the bag over an hour before placing him inside. Its day two of the new tank and he seems happy and active as ever. My question is how often to I need to change the water? I currently do not have a test kit but will be getting one within the next few days. Im new to this and don't want anything to happen to the little guy. Hes a red veiltail. Also, how often to most feed the Betta? I have read many diff things ranging from twice daily to once to everyother day and skipping a day completly. Currently using HBH Betta Bites and Tetra freeze dried blood worms. (Ihave only given the blood worms twice as more or less a treat. Just a few at a time.) Also, added to the tank water when first filled was Betta h20 conditioner. Any help is apperciated. I love this forum and all the wonderful ppl. Everyone has been SO helpful so far in the new journey with my Betta and I can't thank you guys enough!!!
