I have had all three types of GG red tail beautiful and does not grow as fast a the albino ones,but they tend to be more aggressive then the others I have a male 24 inches and a female about 12 inches they also eat more of a fish and krill and carnivore floating sticks.The white one are more vegetarian than the red tail ones and the all grey ones are the same as far as diet.I have had huge white ones before and even kept it with small African cichlids.I would say that the albino ones grow twice as fast as the red tail ones.I bought a small albino from Pet Land for $14.99 its about 4 inches long,I am going to put in the 400 gallon tank when it grows out to about 12 inches hopefully it will get along with the other two red tail ones.
