He is about 5 inches. My blue is about 5 inches and the yellow almost that big. The tomini is the smallest of the three. The male squareback is also bigger than the blue tang almost so thats alot of 5 inch fish. lol My current tank is actually pretty happy as far as temperment, the only aggression I have is that all the fish chase the blue reef chromis once in awhile.
i also am on the active look out for a 180g or a 220g for the somewhat immediate future upgrade. So capacity wise I should be good.
Do the purples tend to be aggressive or are they easily bullied? I've read both so not sure which is true. They are a sturdy tang as well, not ich magnets like the blues are?
Sorry so many questions, I just wanna be 200% sure before i take the plunge.
Thanks for such a quick response melosu! i so appreciate any help or suggestions you make! What kind of tang were you considering by the way as your 4th? or still unsure? lol
