I just got a brand new betta named bebe yesterday evening. She was very active and exploring her tank.
A week ago i had bought a betta named Marsden. Marsden died within 2 days. Upon putting him into the tank at first, he was very engergetic and loved exploring his tank & ate 2 pellets. By the following day, he would not swim into the deeper depths of the tank, remaining at the top all day. He also had no interest in food. Day 2, he had not moved, only lifting his head every 10 minutes to get a breath of air. We bought a thermometer & heater, to discover the tanks temperature was at 76 F , right about where it should be. He also acquired white stuff on his body/fins and everytime he did attempt swimming lower, he just floated right back up. He passed away later that evening, sinking to the bottom :(
I sanitized the tank/rock ornament/rocks/thermometer/heater/plant with 1/9ths vinegar, 8/9ths hot hot water. I rinsed it out and did it again and let it soak for about 30 mins, rinsing it out and letting it air dry. Upon getting Bebe i rinsed everything off again with just hot water.
Bebe now is remaining at the top of the tank, however will swim around, but will remain strictly at the surface. She is not on her side and still eats the pellets and shows interest when im here. She just wont swim down and will remain in the same place unless im infront of her tank!
No white stuff has accumulated on her.
Im not sure if im being paranoid but im just scared its happening to Bebe too! Im new to fish and Marsden was my first, i want to do it right with Bebe and do all that i can to make sure shes healthy and happy!
Any ideas? Am i just being paranoid???!
