Ive got four of them. Had 5 but one didnt make it. He was in bad shape when I got him.
if you dont want him, I would help you out and take him for you, lol
These are my all time favorite fish. I dont know what you have it with, or size tank, temp of it, etc. But some can be kind of agressive, and some can be laid back. All depends on the one you have. Out of my 4, I have one thats kind of mean, the rest are pretty laid back.
But what ever questions you want me to answer I'll be more then happy to help.
