I currently have a 56g tank and I have three small tangs I know that's a no no but it was only like 5 months and now I have my 210 up and going. I have a blue hippo, a yellow tang and a powder blue. Right now the powder blue is agressive towards the others but the yellow and blue get along good. I'm going to transfer them into the bigger tank. Is there any special order I should do this to keep them has peaceful as possible?
