I rescued a iridescent hm betta from petspart like 2 weeks ago i named him yuki. He was in a tiny cup with half of the water basically evaporated. As soon as I got him home i scooped out water from my other betta's tank into a holding container and put yuki in there while i prepared his 5 gal tank.
After his tank was ready and temperatures were ideal i put the holding container for like an hour so he could acclimate to the temperature in the new tank. He would swim around, explore, do wigglie dance, and swim towards me when i got close to his tank. Everything was great till last night.
He started hiding behind the filter and playing dead. Like it really looks like he's playing dead. At first i thought he was dead and i panicked and was sad cus i couldn't believe he would just suddenly die. But then i leaned in closer to the tank and he would swim out to look at me and do his wiggle dance. He's been doing it all day yesterday and today... it's driving me nuts.
He'd go behind the filter and look like he's dead. Like vertical-ish wedged behind the filter and the wall of the tank. Sometimes he would float up on top sideways like he's belly up, again behind the filter. I tried to take a picture but every time i get close to him to try to take a picture he swims out all happy. He's also made a bubbles but not in a nest form, just bubbles all over the place.
anyone know if he is sick? or just messing with me T_T
