Here's how to properly choose fish for your aquarium once you get to your tropical fish store. What you are looking for is general overall health. What you want to look for, make sure that the fish are breathing properly, that there are no outward signs of any kind of disease or any kind of damage to their fins or body. You would also like to go ahead and ask the tropical fish store in question to actually feed the fish and see them feed on demand. If the fish will not respond to those foods, you of course do not want to buy that fish immediately. Typically on a tropical fish store it should only take anywhere between a week to two weeks for them to acquire a new specimen for you. Once they get the new specimen for you, you want to also go right ahead and take a look at the stomach area. If the stomach area is pinched in, or it seems that it's skeletal in nature, of course you don't want to buy that fish, that fish unfortunately is not going to do well in that aquarium for you and it possibly will not eat. There's also a very good possibility that it might have an internal parasite which is not going to allow it to go right ahead and actually receive the nutrition from that food that you're feeding it.
