I currently have an old Angel fish (the one in my avatar) thats about 5 years old. She is 4" long and about as high, and I was wondering is this is considered "large". I was the pet store today and I saw 3" Angels labled as "large" going for $12, and ones labled "small" for $3. The small ones were about the size of a quarter. Now my question is, are the "small" ones just babies and will eventualy get as big as my current one, or is that they're full-grown size?
