A few Angel questions

I'm going to inherit three young Angelfish(P. scalare), amongst other critters, from a kid getting out of the fish hobby. :grinyes:
I have a 47 breeder and an appropriate filter just laying around, so I thought: why not take them?

Anyway, when measuring the volume of the tank- it is quite shallow- it came up as 17 inches tall. One or two inches of this will be gravel, and there will be about an inch from the surface so I can keep the light on the tank, but this leaves them only 14-15 inches of height to swim in. It is my understanding that Angels only get about 10 inches long, but... would this leave them enough room? I won't take them if this is too small.

Onto another note- I would love to keep a pair of Rams and a school of Cory cats with the Angels; from what I've read, they get along well, but you can never be too safe!

Finally, will they leave plants alone? I would love to try my hand at a South American/ Amazon biotype, with plants like swords and vals, but I know how cichlids can be with plants

I'd love to know this info soon, since I'll be getting the fish next Thursday. Will be setting up a quarantine tank first.

Thanks c:

*EDIT* Sorry, guys, but I'm super-new to the forums, and just noticed the Discus/Angel subforum. Can somebody please move or delete this? D:

NOTE: When I derp'd and said that Angels should, in my understanding, only get about 10" long, I meant tall- from the tip of the Dorsal fin to the tip of the Anal fin. :wall:

Sorry for the late replies. Exam week isn't forgiving.
Anyway, I have the main tank filled up. May be nixing the Cories, as the only substrate I could get my hands on was pea gravel. I would have loved to use pool sand, but I couldn't go to town and buy any.
I'm not following the inch-of-fish-per-gallon rule; in fact, I was mortified when I had a classmate ask if she could buy a 10 gallon tank and stick one or two Blood Parrots in it! Knowing that Angels are peaceful, and that I have an oversized filter, I didn't know if I could sneak in a few small fish. I've been reading a lot on Angels the past few days, and have seen many mixed feelings on tank size, with some people keeping pairs in tanks as small as 30 gallons. As I've never worked with Angels, I didn't think it would hurt to ask.
If the Angels end up being Veiled or Altums, I'll switch them with my Parrot Cichlid's 55 gallon tank. But, as it is, the tank only has an inch of gravel, so they now have an approx. 15" of height.
The only problem I have so far is that I have yet to buy plants, the bulb in the fixture is... sub-par... and, most tragically, my HOB filter has something wrong with either the impeller or its housing, so I have to replace it. With the cost of the plants, filter, and bulb, it looks like I won't be getting another Boa Constrictor sp. at the next reptile show. Sorry, Zorro, my little Colombian Boa, but you'll remain a bachelor for a few months more!

Just an update for everybody following this thread-
I contacted the kid a short while ago about the angels, only to find that they had croaked.
However, he also had a bunch of Tinfoil Barbs, an Oscar, Pacus, Silver Dollars, Plecos, and a catfish I could have! Honestly, I thought the ANGELS would have been big enough, but... Geez. I can't figure out WHERE he bought them. Sans the Oscar and the Pacus, I haven't seen any of those other monsters at the local LFSs. They weren't exactly small, either.
All of these big fish have me looking for smaller livestock now, so I'm draining the tank and converting it into a Paludarium for some assorted nano fish and some kind of Hylid frogs.
TL;DR- we can all stop worrying about the Angels now. It makes me mad that he managed to kill them, but also relieved that I don't have to juggle tanks anytime soon.
