Penny my beautiful CT female has been acting sooo strange the last 3 weeks. She first burrowed herself under some stones, and freaked herself out, then a few days later jumped outa the vase! Every since then shes had clamped fins, and i have not gotten to see her glorious tail spread out! She is eating just fine, she still jumps for a pellet and gets excited when I get near the vase.... She has a tera cota pot in her vase, and when im not around she always hides in it and lays on the bottom inside the pot! She has never done this before, its scaring me :( I know fish like to die in a dark place or whatever, but i really hope this is not the case. The Vase is not heated, but i live in Florida, the water cant be less then 73-75º. Also she has been in there since i got her a few months ago with no problems. Do you guys suggest i do anything?
