Aquarium Advice Regular
Hi all... I found this site through Google and thought it looked like a good place to get some of my questions answered. I've had my first tank here for just about one year and I've noticed that some of the fish I've purchased, which I usually buy in at least quantities of 2 or more, have noticible size differences over time. When I buy the fish, they are close to the same small size. Over time, one seems to grow quite a bit while the other seems to not grow hardly at all. The fish I've really noticed this with is my Albino Chinese Algae Eaters, Albino Cory Cats, as well as my Albino Rainbow Sharks. (I have 2 of each of these kinds of fish) The smaller fish in these pairs seems to hardly have grown at all since I bought them and the larger one's seem to have doubled or almost tripled in size. I know that sex can dictate the size of the fish sometimes but I'm not sure how to tell one sex from the other in any of these species. All of the small one's look identical to the larger one's other than the Chinese Algae Eaters. The small one seems to have more of a brownish tinted body behind the head while the larger one has the typical pinkish/orangish body color. Once again, I'm sorta new to the aquarium thing but I am interested in learning more. If anyone has any info on this I would greatly appreciate any help.
