Being a naive new aquarist I purchased a gorgeous pinnate batfish 5 months ago not realizing that they get HUGE and didn't realize that the bigger problem was their 100% mortality rate due to starvation.
To my surprise.....He was instantly an aggressive great eater and beat out my tangs on feeding everytime. He is so healthy, friendly and incredibly beautiful. He seems so fragile, he cracks me up when he stands his ground with much more aggressive fish, of course he is the big daddy of the tank.
I have a 125 and have moved all of my rock to the back of the tank to maximize swimming room, he is fine for now but honestly I love him so much at this point, while I wouldn't buy another one because it's wrong to have such a fantastic creature in captivity I would go but a 200 gallon in a second to accommodate him.
