My vieja synspila is not eating. He's getting really skinny and I'm worried. He is the biggest fish in the tank, but he refuses to eat. I've never seen him eat once! I have seen him poop though, so he must eat. But maybe he has parasites or maybe he's not eating enough. There is a female vieja synspila in the tank and she eats great. What should I do? Do you think if I setup a tank for just the pair of viejas he will be less shy and start eating?
