Thanks, Cassaundra....through my research, however, I have fallen in love with Angelfish. B)
I went to two petstore today (non-chain stores) and got completely conflicting info! The first one told me I could put four (4!!!) Angels in my 20 gallon tank. Full grown!
The second store told me that I could have a few dwarf sized Angels in my tank. I didn't even know there were dwarf size Angels. Then he proceded to tell me that I WANT GOLDFISH. I mean, he actually said that's what I want. I'm like "Uh, no...I want Angels" Anyway, it was quite an experience.
Then I went to see if I could find an Angelfish book. There aren't any! I'll have to buy a book online. I went to PetsMart, Petco, Borders and Barnes and Noble to look for Angel books. Nothing! There were several books on aquariums and general books on freshwater fish, but none provided enough info on Angels. I need to clarify all this conflicting info I'm getting.
I'm pretty sure I want a Koi Angel...but, I want to check out the other types, too. I really might get my Koi Angel from you Knucklhead, but It'll be a while until I do because my 20 gallon isn't even set up yet!
