My son has a blue Delta tail betta. He named him Dinoco Blue from the Cars movie. He has had the fish for about 4 months now. Dinoco Blue has always been active and swims a lot around his tank. He had been in a small Betta bowl, about a quart or so, maybe slightly larger. My 2 daughters each have African Dwarf frogs and they were in a separate full ecosystem cube. My son dumped a bunch of food into the frog cube and it required extensive cleaning which in turn meant separating two different kinds of rocks after they were mixed. That took about 4 hours. After deciding that I was not going through that again I decided to move them into a larger (5 gallon) filtered/heated tank. After talking to the pet store people, they told me I could put the betta with the frogs since the betta would not attack them. After getting the tank ready on Saturday night, letting it sit more than 24 hours all day Sunday, we moved the betta and frogs into the 5 gallon tank yesterday afternoon. They were all ecstatic. The frogs were swimming like olympians and the betta was darting all over. They all seemed so happy to have so much room to roam. Last night I noticed the betta laying on the bottom of the tank. No idea what else to do, I checked the water. All the levels were fine. Nothing was too low or too high. Nothing was in a danger zone. The water was ok. This morning, half expecting my son's betta to be dead, we checked on him before the kids woke up and he was still laying in the bottom of the tank, breathing, but barely moving. The water was cloudy, when last night it was crystal clear. Sometimes he is on his side, sometimes right side up, and other times upside down. I went to the pet store this morning and asked them what the problem is and what I can do to keep my son's fish from dying. The lady told me it was likely ammonia from it being a new tank and there is just not enough good bacteria in there yet. She told me to change out the water again and put in some Betta Ultimate water conditioner in it to make sure there is no ammonia or chlorine in it which the test strips don't test for. I did what she said as soon as we got back home. But he is still laying in the bottom of the tank. He does swim around a little, but he seems very weak. He got too close to the filter intake and it looked like he was suctioned to it. I turned the filter off and he sank to the bottom. He is still mainly laying on the bottom either on his side, upside down, or vertical. But from time to time now he is swimming a little. Not long, but a little. What is going on? Is Dinoco Blue going to die? Is there something else I can do for him? I really don't want to see a sad little boy the day before his 4th birthday crying over his dead fishy. Someone please help me save his friend.
