Good news, CJ is eating again, and he makes his bubbles and he putzes around the tank and through his plants... he now will eat a couple pellets a day, the eat spit eat spit way my old fish did. He will also finally enjoy one of the freezedried bloodworms now and then, he loves to attack them!
I guess he just had to have time to adjust to his new surroundings. I know most of you think my 1.5 gallon is too small, but he seems to love it. Compared to the tiny cup they had him in, it's a palace haha. And look at him, with his white face he was only one of few that were left before they restocked their beta supply so I think people just didn't like him and he lived in that cup for too long.
So all good news! I thought you might like to know. Thanks again for the input, I enjoyed reading it.
