Dear BettaFish.com community,
My boyfriend and I are new betta fish owners. We bought 3 bettas (one male, two females) and put them in the Fluval Edge Aquarium (http://www.fluvalblog.com/fluval-edg...tional-launch/
). We bought the aquarium and at the store we were told to prep the water using the different water-prepping solutions that were included in the Edge package and have the water prepped one week before we put the fish in. When the week was over, we went back to the store, brought a sample of the aquarium water to be tested to make sure it was okay, and they told us that we could put one male and two female bettas in the tank.
They said the water was perfect and the aquarium was ready for our fish. For the first couple of days, the fish were acting normal and eating regularly. We were told to feed them about 5 fish food flakes (which they were fed at the store) once a day. A few days ago, however, one of the females stopped eating. At first I thought she was just a bit slow and didn't get to the food in time before the other two gobbled the flakes up. But at one point she went up for air, and a flake was right above her mouth and she didn't eat it, she just ignored it. Upon further observation, I also noticed that she wasn't as active as the other two, spending most of her time at the bottom of the tank and going up only for air.
Today, my boyfriend decided to take her out of the tank and put her in a small bowl by herself to see if she would eat at all, and she didn't eat anything. I'm not sure how long betta fish can go without food, but I'm worried she might be sick or depressed and is starving herself.
The tank has 6 gallons (23 liters), 3 live plants, LED lights, filter and aquarium gravel. We have only had the fish in for about a week and were told that we could do a water change once a month, so no water change has been done since we got them.
