How quickly do angelfish grow?

[Caspian]

I just bought 2 small angelfish from my local pet store. The employee assured me that they'd do fine in my 20H tank, but after bringing them home and researching angelfish care, I've come to realize that they will eventually outgrow my tank.

Now, I don't imagine this being too big of a deal because I plan on purchasing a larger tank eventually. But how soon will they need to be moved to a larger tank? When will I know it's time to get a larger tank?

Thanks!

2 angels in a 20 gallon high should be ok. I have angels that started off dime sized and grew to half dollar size in 2 months. When they are small they grow fast, mine slowed down after they hit the 1 1/2 inch mark.

Ok, thanks. So, I'll leave them in my tank for now. But I assume I'll need a larger tank eventually since they will grow up to 6 inches in length. Will this happen in, say... a year? Two years? I'm just trying to get an idea of what sort of time frame I'm looking at.

I've never seen an angel that big lol. I've seen 4" and they looked huge to me lol. I'm assuming if they were going to grow that big it would take a few years. Angels usually grow taller than wider.

Oh! I guess that's what I get for reading random sites on the Internet .

Thanks so much for your help!

Don't get me wrong, it's very possible for them to grow that size, but it would take a long time. I've had my bigger angels for almost a year and they are only around 2"

Ah, thanks. I'll be getting a large tank (75-100 gallons) eventually... probably in a few years. I'm very happy that it appears I won't have a problem having enough room by the time they need it .

A lot depends on there growth rate but from what I see they are not quick growers IMO.

My black angels went from dime size to 6" in 10 months

^ woah you must've been feeding them miracle grow. Lol. That's unusual for angel fish. I just rehomed one of my silvers, I got him when he was dime sized like 2 months ago and he was half dollar size when I gave him away. I have 4 marbled that I've had for almost a year and they are barely at the 2" mark. I think temperature has a lot to do with it too, higher water temps speed up their metabolism but also decreases their life span.
