15 gal

Thanks everyone! I got them (male and female) and they're just gorgeous! Their bag is floating as I type. Should I feed them special cichlid food (pellets)? If so I can run out an get it now.
Give them a day or two before you feed them.
 
Checked in the tank this morning- my female passed away during the night :( They have a warranty on the fish at my LFS, so I have to take her in today...

On another note- the male seems to be very healthy. He's swimming about this morning. I fed the cories their wafers today, and he's eating the one they haven't noticed yet. Last night I dropped a fresh, de-shelled pea into the tank... the female ate some of the "crumbs" that floated by her mouth, but the male went crazy attacking the pea on the bottom of the tank. I think he'll do just fine.
 
My LFS tested my water for me (they had me bring in a sample w/ the dead fish) And it turns out that my pH was very high. They said that it may have had something to do with that, so I got some stuff to lower the pH. it's from API, and called pH proper. It will set the pH for 7.0- I'll add it to the tank tonight.
 
Hello, Lexi_D:
I hope you can read this message soon, because I am worried thinking that any change on pH (increase or decrease) should not be greater than 0.2 in a 24 hours period. So, if you are going to lower the pH of your tank's water, keep this in mind and do it slowly.
Bye!
 
I think you need to do a slower acclimation. And do not adjust the pH with the chemicals.

If your goal is to breed them and raise fry, get rid of the cory and have another tank for the fry.
 
I only had the male, but I found him dead this morning. All params check out ok. I just don't think the species is very hardy. Could I possibly get bolivian rams instead? I heard they were easier to take care of.
 
I'm having much better success with my Bolivians than I had with the Blues.
 
Bolivians tend to be a bit bigger than GBR's I would say a 20 long minimum for two.
 
Bolivians should be in about a 20 minimum, I agree with this. I wouldn't even put GBR in anything less than a 20 if you want them to be kept with other species because of aggression. I have a breeding pair of BR in a 75 gallon but the fry have never made it, heck I'm not sure if the eggs even got that far.

One major problem with GBR anymore is that they are often hyped up on hormones when you get them, some die in the acclimation process because of this but quite a few get through fine. My first pair were petco finds and were up on hormones, the female died the next day and I got another "female" which turned up to be a male. They went into a 65 gallon after that and I got myself a new pair from a more reliable LFS, not near as colorful in the store but once I got them home they colored up nicely. If you look at the pictures in the second link that Artemis JT posted you'll see my second pair.

GBR aren't that hard to take care of once they get past the acclimation stage. They should be kept in a well established aquarium, so add them last if you want to get them, and don't add chems to help with water chemistry because the fluctuation in ph is usually far more stressful than having them adapt to your current ph. As long as your ph isn't way up there around 8.0 you should be fine, and if you want a more stable way to lower it then put some bogwood in there, that keeps it low and won't dissapear after a wh89le.
