Hey guys i just upgraded my little fish bowl into a 2g tank and i transferred my betta fish into the new tank. He seemed to be active when he was in his bowl but now he is just lying in the surface (sometimes he is going down to the bottom of the tank). He is less active now always hiding in the silk plants i bought him and lying in the surface. He would not eat. I'm really freaking out right now.
One thing i noticed when he is in the surface sometimes he will sink but watching this makes me laugh, LOL. I don't know what happened. Need some advice guys. :))
