Contemplating Angels

[fishboytoo]

Hello Cichlid Lovers!

I have been thinking about getting an angelfish or two for my 20 gal tall tank. I have been doing some research and I come up with a 10gal/adult requirement. I am wondering if this tank would be suitable for two angels and 4 small cories who currently reside in it. Would two angels be okay together in this tank? I'm not intending on a breeding pair, just two picked randomly from the store. Would a lone angel be overly aggressive?

I have also been getting different max sizes for angels ranging from 7.5cm to 15 cm, what is the more reasonable adult size?

Has anyone heard of Pterophyllum leopoldi? From what i've read, they have a max size of 4". If I could find those I would think the tank is large enough. Otherwise I'm looking at P. scalare, and I'm doubtful that the tank is adequate.

Thanks, in advance.

I keep angels and I think you're right that they wouldn't go in a 20g. The ten gallon rule seems to be a bit iffy to be honest, I've also read that you need 12" length for each angel in a tank of at least 18" high, and 12" deep, and I don't know how accurate that is (and again I think that "rule" is a bit iffy as you wouldn't keep an angel in a 12" tank). I do know that you need a tank of at least 18" high though.

As for their size, my older juvies are about 2.5" in body size alone - I'll see if I can measure them properly for you.

I've heard of Pterophyllum leopoldi, but have only seen them once on Aquarist Classifieds - I don't know how easy they are to get hold of.
