Preparing For German Rams

[molver]

Hi,
 
I have a 20 gallon aquarium that's been set up for about 2 and a half months now. 
 
I have 3 swordtails, a molly, 6 neon tetras, 3 corys, and 1 oto. 
 
I want to get a German Ram, but I'm having a hard time getting enough information about them.
 
So my question is: Is my tank suitable for a german ram?
 
I consider myself a beginner, and I don't know how difficult they are to care for.
 
I also plan on getting about 3-4 more mollys in the future, and maybe 2 otos.
 
Will I be overcrowding my tank with this population?
 
Thanks!
 
*edit: I'm not sure where to post about German Rams, so I posted here in the general forum.

Blue rams are a very delicate, sensitive little fish. They need very soft, very warm water (around 28°C) that is low in nitrate.
 
Your mollies and swordtails, on the other hand, need quite hard water and don't like it too warm, so one or the other species isn't going to be happy.
 
What's the hardness and usual nitrate level of your tap water?

Your tank is also really new. I would not have the rams in this tank because it's so immature. 
 
Just checking, did you cycle this tank fishless?

Yes I suspected my tank might not be established enough to support rams.

I'm not sure about my water hardness, how can I find out about it?

And I don't remember my nitrate level, but I tested it a few days ago, and it was in a safe range.

I guess I'll just wait a few more months before going for rams.

You should be able to find the hardness of your water on your supplier's website.
 
What's the actual level of nitrate, both in your tank and straight from the tap?

If you have a PH over 7 and/or anything over medium hardness then I personally wouldn't even bother trying.
My GBRs have been perfect but they live in soft water and acidic 6.2 PH
 
I think a lot of the Asian imported GBRs have in the past been injected with hormones and other unnatural things to make them more colourful which has probably weakened the captive strains over time.
 
If your conditions suit, you have a stable cycle and are prepared to do regular PWC then they're lovely fish and worth the effort

I still have to figure out my water hardness and have to retest my water for the nitrate and pH levels.
 
I'm busy with midterms this week, so I'm gona put this off for the week at least.
