Rainbowfish Temperature and Compatibility

Hello, all. I have another thread going in a different section where I'm trying to decide on a schooling fish to add to my tank after some loss and issues in my tank. There's been some difference in opinion on that thread and in online sources that I've been consulting regarding my question, so I figured I'd bring it to the Rainbowfish section to see what I get. I welcome definitive opinions from those who have weighed in on my other thread as well as new folks with definitive opinions.

So, I'm looking at Australian Rainbows as my schooling species. I prefer larger, bigger bodied fish, so I would prefer these guys to smaller schooling species. The main issue, though, is temperature. My tank seems to average around 79F, and depending on weather, etc I've seen it fluctuate between 78-80. According to opinions I'm getting on my other thread, this is too warm for these guys. Yet, I've seen some other information that would suggest otherwise. I'm just looking for some more opinions on whether these guys would be a good fit or not. Tank specifics are below.

55 gallons, cycled.
7.6-8.0 PH (it has fluctuated)
0 ammonia and nitrites
5-10 Nitrates
Current stocking: 1 Blood Parrot and 1 Krib.
Future stocking: 1 Angel, 6 Emerald Green Cories, and I'm hoping 6 Australian Rainbows.

 

I beleive79 is as hot as their natural environment gets and it gets down to the 60s, so you i'd call this quite hot.

 

Thanks, Plecomaker! So, do you think my water is too warm to try this, or do you think it will be ok, but just barely?

 

Ithink itstiohot and maybe too small.
ifyou could drop thetemp a fewdegrees and drop the angelfish, who won't like the lower temp, you might be able to get awaywith it.

 

Ok. Unfortunately, an Angel is a must have, so this may not work. Another (very trusted) member has told me that most Australian Rainbows that are sold are mislabeled and are actually Eastern Rainbows. The same member (and a few others) says the Easterns would be fine in my tank.suggests I'd be way overstocked and under filtered with the Easterns, but the very same member saysis THAT inaccurate and that I'll actually be fine. To me, that's a lot of conflicting information, and I'm just looking for a few more opinions first.

 

By all means

 

Plecomaker, do you know about the differences between the Australian Rainbow and the Eastern Rainbow? If so, do you have an opinion on how it would work in my tank?

If I have to reconsider, I really don't know what I'll end up doing because I've racked my brain, and I've done the same to many folks on here. The issue is, I really want to find a fairly large schooling fish. I also would like colors closer to earth tones, get something that will pop and not be too difficult to see.
